I have a speckeled sussex about 9 months old. She hasn't layed in about two weeks. Her behavior has been fine until today. She usually doesn't let us touch her but we were able to hold her and pet her to feel her body. She is ruffled and listless. She won't even eat yogurt. Isn't roosting with the other girls just sitting alone. Her face is not swollen from what I can tell. I put some apple cider vinegar in the water for all the girls tonight as a precaution. Doesn't feel like she has an egg in her and no bulge on her crop. Not sure what to do!? The other girls seem fine, I don't have a way of separating them. I can't tell if her poop is abnormal. She is pretty fuzzy on her vent so the poop I can see looks normal. Any ideas?
