Czech's_chicks :
If you use these methods and the worms are expelled....what is tokeep the chicken from rummaging around and eating those same worms again?
I have at least 1 infected with an almost translucent worm that is like a blob but stretches out. Found it in some droppings. This was in the yard with the free rangers. over 50% of them were purchased at 3+ months from someone else. No sign in the penned birds.
I have Ivomec, but cannot remember the withdrawl for meat and eggs. How long after treatment before we can eat the eggs or meat?
Are you sure that was a worm? I found something like that in some poop and the consensus was that it wasn't a worm at all, but some tissue from the gizzard or something along those lines (wish I could remember-will have to see if I can find the thread).
Withdrawal is up to you. Most use 2 weeks. There is no "accepted" withdrawal since it is an entirely off-label use. I don't even do two weeks, personally, but I make sure the eggs don't go in a carton that anyone other than my DH and myself would get.
ETA: Here is the thing that my rooster pooped out--could be cecal lining, I was told. Thought it was a cocoon, ick. They poop out all sorts of stuff, tissue and the like, that aren't worms.
