I get lots of questions on my Facebook page about chicken feather loss, usually asking how to stop it, but before any solution can be offered, the underlying problem must be identified.
Feather loss and bald spots are often the result of stress-related conditions that must be fixed so that feather picking does not degenerate into a flock-wide problem.
Chickens are cannibals and they learn to pick from each other, so ending unwanted picking as soon as it begins is critical to avoiding a bloody epidemic.
MOST COMMON CAUSES OF FEATHER LOSS
Bald spots are common in chickens during a molt. Molting is the natural, regular shedding of old feathers and growth of new ones. Molting occurs at fairly regular intervals for each chicken, and ordinarily begins as daylight hours shorten at the end of summer, however, it can occur at any time due to lack of water, food, or sudden change in normal lighting conditions.
Broody hens tend to molt furiously after a period of broodiness Chickens molt in a predictable order beginning at the head and neck, proceeding down the back, breast, wings and tail. Chickens are vulnerable to pecking during a period of feather re-growth due to the visible presence of blood in the newly emerging pin feathers.
Learn the normal molting patterns of flock members so that bald spots due to molting are recognized as normal. Be alert for broken pin feathers and pecking from other flock members. Separate any bird with damaged or bleeding pin feathers from the flock to prevent further injury.
A broody hen is one that is inspired to sit on a collection of eggs until she hatches chicks. She plucks her own breast feathers to expose the warmth and moisture of her skin directly to the eggs, hence the expression “to feather one’s nest.” After a period of broodiness, a hen’s hormones begin to return to normal levels as do her eating and drinking routines, all of which results in the loss of large amounts of feathers.
Break up broody hens that will not be permitted to hatch eggs to stop the hormone roller-coaster and prevent a prolonged interruption in normal eating, drinking and elimination routines.
After a hen has hatched chicks, feed her and her chicks with starter ration, which is higher in protein that the layer feed she had been eating prior to becoming broody and will help supply her with the protein and energy needed for feather re-growth.
A chicken is naturally inclined to forage for food by scratching and pecking at the ground. When too many chickens occupy too small a space, pecking opportunities are limited and chickens get on each other’s nerves.
Aggression can result from overcrowding which leads to feather picking and cannibalism. Birds with little personal space will also begin picking at novelties on one another such as a fleck of dirt, a feather shaft, or an insect. Innocent exploration very easily results in small skin wounds.
Chickens are drawn to the sight and salty flavor of blood and one small skin wound can quickly become life-threatening injuries inflicted by many chickens. By nature, chickens are cannibalistic- they can and will kill another chicken.
Space is one of the keys to happy, healthy chickens. The bare minimum space requirements are four square feet per bird in the coop and ten square feet per bird in the run. If chickens will be confined primarily to the coop and run daily, a much greater space allowance must be made to avoid feather picking and boredom.
Just as with children, bored chickens will get into mischief. Chickens that are confined primarily to the coop and run daily are more inclined to begin feather picking out of boredom and curiosity than free-range chickens.
Free-range chickens seldom run into trouble with boredom, but when inclement weather prohibits free-ranging, boredom-busting activities can be offered.
Chickens kept on a restricted feeding program vs free-feeding regimen may become bored in between feedings, leading to feather picking and problem pecking.
Same solution as overcrowding, above and introduce boredom-buster type activities. Growing sprouts is a great way to create a foraging opportunity for chickens.
Provide feed in crumbles form instead of pellets to extend the amount of time birds spend procuring feed to satisfy their appetites. Treats or snacks can be employed as an occasional distraction, but should not be relied upon as a primary form of entertainment.
No more than 5% of a chicken’s daily diet should consist of extras other than layer feed as obesity is a major problem in backyard laying hens.
Free-feed chickens instead of rationing their food several times per day. Being allowed to pick up small amounts of feed often throughout the day eliminates competition for feed and provides an activity with a purpose.
Adding green, high-fiber treats such as kale, cabbage, etc. to a brooder or run can help alleviate boredom, but always ensure grit is available (sand, for example) to help digest fibrous foods and remove treats after 15 minutes.
Chickens that are deficient in protein, sodium and/or other dietary essentials will seek out sources of the lacking item to satisfy their nutritional needs. The deficiency can cause a chicken to peck excessively at their own preening gland, the feathers around it and feathers of other birds. Protein-deficient birds may pick and eat feathers.
Feeding chickens too many treats/snacks/kitchen scraps can interfere with daily nutritional requirements, causing aggression and problem picking behaviors.
Provide a nutritionally complete feed appropriate for the age of the bird. Limit treats/snacks/extras to 5% of their total daily diet. Treats should be limited to healthy, high protein, high fiber choices.
When a rooster assumes the mating position on top of a hen, he balances himself by holding onto her neck feathers with his beak and standing on her back (also known as treading).
Over time, treading can result in feather loss to both areas of the hen’s back. Roosters can favor particular hens, giving them more attention than others, thereby causing excessive damage to their feathers and skin.
Ensure a reasonable rooster-to-hen ratio of no less than ten hens per rooster. Trim or file a rooster’s nails to minimize feather and skin damage to the hen. House the rooster apart from the hens or pen his favorite hens away from him when necessary.
Purchase or make a hen saddle for the affected hen. A hen saddle is a cloth cape worn by a hen for the purpose of protecting her feathers and skin.
Mites and poultry lice damage the feathers and skin of chickens, often causing bald spots. Irritation from these external parasites causes a bird to pick their own feathers and skin to obtain relief.
Monitor the skin and feather health of birds routinely for external parasites. Provide dust bathing areas for birds to maintain the health and appearance of their skin and feathers. Loose sand or dirt are sufficient for dust bathing purposes- no additives are required. Treat all birds and coop when an infestation is discovered.
NEST BOXES- TOO FEW OR TOO PUBLIC
Too few nest boxes: Hens will fight over nest box space, using their beaks to express their preferences. A shortage of nest boxes can result in feather picking and injuries.
Too public: When a hen lays an egg, her cloaca becomes visible as it escorts the egg out of her body. The sight of a red, moist cloaca can attract curious flock members who naturally investigate by pecking the area. This can lead to picking, injury and cannibalism.
Make available one nest box for every four hens in a flock. Keep the nesting area dimly lit and private. Hang nest box curtains to ensure privacy, reduce stress and keep the cloaca from public view during egg-laying.
Egg laying is a particularly vulnerable time for hens. Nest box curtains provide privacy and safety.
TOO MUCH LIGHT
Lights that are too bright or lights that are kept on too long can cause boredom, stress, aggression and picking. Lights kept on in brooders 24 hours per day often result in chicks picking themselves or each other.
Limit the number of hours of light hours to 16 per day for chickens of all ages. If using heat lamps in brooders, only use red light bulbs. Ideally, a brooder will contain a radiant heat source that does not employ light at all, such as the Brinsea EcoGlow, which will allow chicks to benefit from natural diurnal sleep-wake cycles.
OVERHEATING, Particularly in Brooders
Just as people can become irritable and prickly in the heat, so too can chickens. Chicks in brooders are at particular risk of being overheated when heat lamps are employed and overheating can result in agitation and pecking.
One solution is to provide a large enough brooder to permit chicks to escape the heat when needed and monitor the brooder temperature. More about brooder heating here. Another solution is to use a radiant heat source for keeping chicks warm, avoiding any possibility of overheating entirely. Brinsea EcoGlow brooders are one such radiant heat option.
Many of the above cited conditions fall into the catch-all category of stress. Chickens do not manage stress well and it can result in feather picking and cannibalism.
CARE OF INJURED BIRDS
Any time a bird is injured from feather picking or the skin is compromised, the bird must be housed separately from the flock until the injury is completely healed to avoid further injury, cannibalism and death. Much more about the care of an injured chicken HERE.
