Bad Egg in the incubator- a Ticking Time Bomb.

Hatching addicts who have come across a rotten egg in their incubators never forget the smell. The odor is distinctive and unmistakable. Rancid does not begin to describe it.

Hatching addicts who have come across a rotten egg in their incubators never forget the smell. The odor is distinctive and unmistakable. Rancid does not begin to describe it. Why do incubated eggs go bad? Often, dirty eggs are the culprit. Bacteria from a dirty egg grows inside, turning the contents into a foul liquid, killing any embryo present. Gasses build up and generate pressure that may cause the egg to ooze or explode.

I rescued this egg from one of my fairweather broody hens,  who had abandoned her nest after two weeks of sitting. The egg was no longer warm when I found it, which didn’t give me much hope for the embryo’s viability, but I placed it in my incubator hoping for the best a few days ago. Upon inspecting the eggs that had begun to hatch in the bator this morning, I immediately spotted the telltale, maple syrup-looking ooze that strikes fear into the heart of every hatcher. I knew what that innocent, honey-like substance signaled as I had seen it before. A stink bomb in danger of detonation. Must. Act. Quickly.

I took the egg out of the bator and placed it in two, zip-top bags and took it OUTSIDE. I’m just not a risk taker and the smell of a rotten egg is so pungent it could very well penetrate the confines of two sealed, plastic bags.

I always insist on knowing what lies within, so of course, I had to perform an eggtopsy (ie: crack that bad-boy open). My weapon of choice for this job is a heavy carving knife. I tap the blunt edge of the knife against the wide end of the egg (where the air sac would be) to crack it, being very careful not to puncture the bag.  A nice, ripe egg will explode with balloon-like force and sound.

This egg, while rotten, did not explode. There was a well-advanced, decomposing embryo inside that, if given more time in the incubator, would have deteriorated further into greenish-black, liquified putresence. While I’m not ordinarily one to spare the photographic details of the graphic, I thought better of it this time. (you’re welcome)

When candling eggs, pay attention to any smell inside the bator to catch rotten eggs early. Bad eggs readily identify themselves and should be removed immediately.

Happy hatching!

Thanks for the information about the wax substance. I thought my fan was leaking oil, but you saved me from cleaning the rotten eggs anymore.

Thank you for your replay.
I removed the oozing eggs and cleaned the incubator from the leakage. The larvae/worms where not in the eggs themselves however. They where wiggling about in the incubator and on the oozing eggs. Could those worms/larvae be from a fly or are those actual worms.

If so, could you suggest me a de-wormer. For, I am deworming my chickens regularly once a week ( I was advised to do that since I am letting my chicken run free around) and am now fearing that the product I am using doesn't work.

The worms where not in the egg but in the incubator. I cleansed the incubator and the eggs. Could it have possibly fly's laying eggs on one of the oozing eggs?

Your hens are severely infested with worms if they are in the eggs. You need to de-worm them.

Hello,

Its my first time incubating eggs. I got worried when I started to smell a bad oder coming from the incubator. So, I candled the eggs and while doing that I found 2 eggs oozing. However, the most disgusting thing was that there where very fast moving and clear larvae/worms wiggling about. What shall I do and what are they.
