We have six 5 1/2 month old chickens, one of whom is always sleeping now. I've read through a number of posts here, and just wanted to see if there was anything else out there. Other than randomly falling asleep anywhere, and resting on the roost inside the coop when everyone else is outside, she seems fine. I can't find any signs of trouble near her vent, don't feel any swelling or excess heat anywhere, etc. None of the girls has laid an egg this week - but were beginning to lay prior to that - but that is the only other thing that's been going on in the coop. I'd appreciate any ideas or insight! Thank you!!
