well now you have experienced it. I have two hens who will not eat meat with other hens in the area..they know they get beat up, so they ignore it and follow me knowing i will give them some in a different place.I've had molt before. Just NEVER saw ANY chicken refuse to eat meat....under any circumstances.
For me, that is a warning sign that there may be a bigger issue.
Oh...and I'm "hands-off" on bumblefoot unless I see infection.
