I have a RIR who started going off by herself when they are free ranging. She finds a place under some brush and just sits. Over the past 2 weeks her butt has gotten really poop covered as well AND she stopped laying eggs. We washed her butt off today since it's so warm out and I gave her some feed with plain yogurt. Should I be checking for something else? If she was acting normal, I wouldn't be alarmed, but she has changed her behaviour. She will still come and get treats and she hangs with the other sometimes...just not very much.
