On August 21, 2017, countless chickens on earth will experience a total eclipse of the sun for the first and only time in their lives. The period of time during which the moon will cover the sun to varying degrees depends on where they live, but the “path of totality,” or the complete lights-out when the moon totally blocks the sun from the earth, will last only about 2 minutes and 40 seconds. What does that mean for your backyard chickens? Should you take any special precautions, worry about their behavior, be concerned about their their vision or fear a drop in egg-production? The short answer to each is: no, so relax and enjoy the celestial show!

VISION

The electromagnetic radiation from the eclipse will not cause blindness in your chickens. While it’s true that retinal damage could occur to chickens who look at the sun directly at any time other than during the sun’s complete eclipse by the moon, chickens are not in the habit of staring at the sun and there is no reason to believe they will begin gazing uncomfortably into the sun during a solar eclipse.

BEHAVIOR

You don’t need to worry about your chickens being outside the coop during the solar eclipse. Chickens have poor night vision, which is why they begin to head into the coop to find a safe roosting spot as dusk approaches nightly. As the moon begins to darken the skies during the solar eclipse, your backyard chickens will respond as they would to any other darkening of the skies by heading into the coop. When the eclipse wanes, they’ll likely meander back out for the remainder of the day. The eclipse won’t have any more impact on the flock than the average summer thunderstorm that rolls in with black clouds and rolls out just before dinnertime.

EGG PRODUCTION

We know that day length triggers egg production and decreasing day length negatively impacts it, so are we concerned that the solar eclipse will take a toll on the daily egg tally? Nope! According to poultry veterinarian Dr. Annika McKillop, “The birds will keep laying- there isn’t a large enough change in day length to make them stop laying eggs. If anything, the birds may start to go to roost at night as it gets darker near the time of the eclipse. They will come back outside again after the eclipse occurs as it gets light again.”

Thank you. This is something I would have never questioned… It is good to know the girls can safely go about their scratching with no ill effects.

In case it is necessary, I also am happy to be entered into the drawing for the Brinsea Brooder Heater. I have wanted one of those for some time and haven’t ever felt I could afford it. Even if I don’t win, thanks for the opportunity.

This would be a great, safe option, and I’m glad my hens won’t be affected by the eclipse.

Great blog! This is my first time having chickens and I’m learning a lot. Thanks for the info about the Ecoglow chick brooder. No heat lamps for me.

Hadn’t even thought about the eclipse and my chickens! Would love to win one of these.
