First time finding worm in egg. Help!

[platinumAtom]

Hi, I'm hoping someone can help!

I've had chickens for a couple of years and this is the first time I saw a worm in one of the eggs. I just found out that my husband also saw one of these a week ago. This particular egg had a softer shell and lighter colored.

Recently my chickens have started shaking their heads and laying less. It looks like they are missing feathers now too. I treated them with safeguard (fenbendazole) in June and about a week ago I sprayed the coop with permethrin (followed according to label).

Thanks in advance!

It might not be a worm, it could be a ovum.

Are you familiar with blood spots? Sometimes hens lay eggs with bits of blood or even little chunks of tissue inside. Especially in pictures, a stringy piece of material from the hen can look a lot like a worm, so I can't tell for sure if that's what happened here.

I believe the entire egg is considered the ovum. I agree with @NatJ, what you're seeing here is not a worm but a bit of endometrial lining that had shed and was incorporated into the egg. Let's ask @Eggcessive and @aart if they agree or have any other ideas what we might be seeing here.

I will let others decide what it might be, but it doesn’t look like a worm to me.

No, not a worm.
Meat spot or lash material.
Would need further dissection and in focus pics.

Blood spots are from a blood vessel breaking when ova is released from follicle.
Meat spots are from a tiny piece of tissue breaking loose from the reproductive tract.
