My largest RIR hen, the one that seemed to least appreciate the aprons I had them all in, is not in good shape. I thought she was just moody over the apron incident, but her wattles and comb are pale this afternoon, she isn't eating or drinking much, and she's standing alone a lot. Yesterday it took her until after noon to come down off the roost and out of the hen house I figured she was miffed about the chicken apron I put on her and the rest. I've posted in the past about her "balloon butt" that didn't turn out to be fluid or an egg. Someone suggested this morning that it could be a cyst and to give her antibiotics, and I thought she might have worms but don't know how to tell. She has had some diarrea today, but one of the other hens does too- kind of runny gold color, sometimes runnier with white in it. She isn't panting or laying down, and I cleaned up her bottom and vent area this morning and set her in a bucket of warm water up to her sides to relieve the swollen "water balloon" on her butt. Now with her appetite going south and her color leaving her comb and wattles, I'm afraid she may be in trouble rather than just irritated. Should I give her antibiotics at this point, not really ever sure what's wrong with her?
