They are not free ranging yet I'm afraid they won't come back lol. Do u think I should treat for worms and cocci just in case? Will it hurt them if they don't have it?? And should I treat the adults for both as well?
If you have a vet that can perform a fecal float that would be better.
Treating for Cocci and worms won't necessarily hurt, but no need to treat unless there is a problem.
It sounds like chicken math got ahold of you I think most of us expand, re-arrange, tweak our setups, etc. With chickens you are never completely done.
