I just noticed my hen today with blood running down her backside. I picked her up and her whole vent area is bloody - almost looks prolapsed and swollen. I felt around gently (not inside) to see if it felt like something was stuck such as an egg and nothing. She has had some respiratory issues (wheezing) for the last couple of weeks but was getting better and otherwise has no symptoms and acts normally. It's not a little blood, but the vent looks very enlarged and bloody. Can anyone tell me what might be going on? I tried to post a picture but can't find a way to do that. can anyone tell me how? Thank you.
