A couple months ago one of my chickens got fly strike. As I was treating her I found that her vent had a lot of yellow yolk-like discharge and was irritated and bleeding. I treated her until the skin around the vent looked normal and the yellow discharge was minimal. She seemed fine and I thought she was all better. Today I decided to take a look at her vent to be sure everything was okay. The skin around the vent seems fine, but there was still some yellow yolk-like discharge, though not much, but there was a watery, sort of egg-whitish discharge from her vent. I don't know if she's laying eggs or not because I have no way to isolate her from the rest of the birds without causing her a lot of stress. My guess is that she's not and there's something going on inside that is preventing her from making shells and the insides of her eggs are just draining out her vent...which earlier resulted in fly strike when the discharge got a little caked up by her vent. Has anyone ever seen anything like this before? Any treatment suggestions? She looks and acts perfectly normal aside from this. If it matters, she's a golden comet and about 3-4 years old. Thanks!
