i have a hen who is probably about 2 years and noticed she has swelling in her lower abdomen. I initially thought egg bound but that doesn't seem to be the case. I thought maybe peritonitis. Tried to drain area and got about 20cc of a dark brown fluid lower right quadrant. Tried the left quadrant but wasn't able to Withdraw fluid. I stopped after it seemed it was stressing her too much. I have a call into my vet but probably won't hear back until tomorrow. Want to see if anyone else has had this happen or any suggestions. I attached some pictures too.
