How to tell if chickens have worms?

[annabelle08]

I have noticed a few strips of poop on a few of my eggs recently, is that a sign of worms?? New at this.

Not a sign. To tell if they have worms, have fecal samples read at a vet or your state poultry lab. Where are you located?

The poop doesn't come out with the eggs. The eggs are always laid poop free. There's likely some in the nest box.

Thank you for the answer. I'm located north east of Tulsa, OK. The eggs are always clean, but noticed a little swipe of "black" on 1 egg for the past few days. There is no sign of molting yet, they are all laying every day. 6 chicks, 6 eggs.

Found these tonight in a boiled egg in the white part...
Are they worms?
I bit into one was very tough and like a vein.
If it is worms, will i get them even tho they were boiled?
