I noticed my white leghorn being a little lethargic today. She got into the dog fence and when Maggie started chasing her (Maggie looooves to chew on their tail feathers) she just kinda walked away. Obviously those of you with dogs that chase your chickens will note that is not normal. Especially for her because she is very flighty. When I went to inspect the damage she didn't try to run from me. I noticed some diarrhea(?) on her feathers around her vent. It was runny and brown with a nasty smell. I haven't noticed any runny/bloody poo around the yard or in her nesting box. (Where she sleeps.) When I put her back outside she walked to the corner of the fence closest to the other chickens and laid down. They all ran to greet her. They haven't really been treating her any differently accept they won't sleep in the same tractor as her anymore... Her egg laying hasn't decreased any and her eyes are bright. My whole flock is recovering from lice right now and I just treated them for the second time with permethrin spray. Could this be a side effect of the spray or of the lice itself? I have moved her tractor to a different part of the yard separate from the other chickens. What do you think this is? What should I be doing for her? Also, Maggie got enough of her long tail feathers that you could notice the difference... How will this effect her?
