I have a buff orpington that has not been herself for 2 days now. All she wants to do is sit in the nesting box. She puffs up and has a pulsating vent, I have checked her vent best I could and yesterday she had a lot of fecal matter. She finally had a bowel movement. Today when I checked her there was a little fecal matter. I do not feel any eggs in her abdomen. Her bottom is also red. She does eat and drink some, and only really moves around when I separate her from the others. That is when she will run around to avoid us and also flies about. Please help. I do not know what else I can do and I know that she is miserable.
