Did the vet doing any testing?Update!
I took her to vet a few weeks ago, which left us with basically no answers besides she can return to coop. I was so confused because the vet seemed to think no infection and no vent gleet. I mean, I had done a great job nursing her back to health and fixing the prolapse, but not THAT good.
So I gave them about a week and have returned them to the coop. It appears the mess has cleared up, but she still has a little leakage (more than her sister) from her vent. It’s runnier, more clear, and not sticking to her butt to make a mess. But it’s still concerning me? Any more suggestions on what it might be?
