I have a hen that has poop build up on her behind.. she came to me not long ago and we cleaned her up. It didn't take long and that mess was tangled up in her hair again.. Now she is acting funny. Not participating in free ranging, just being very lonely and boring. At night she doesn't roost and lays by herself on the floor. He comb and wattle is almost non existent and not red, but a pale pink. Should we get rid of this hen to save the rest? Thanks.
