I'm brand new to chicken raising. I have a young flock of 5 girls, only 2 are laying yet. I habe room for 1 more. I saw an add for a Patridge Cochin, 1 year, super pretty. I asked the seller about her and that's when I learned she's stopped laying. Apparently this person just wants to pass her off to someone else instead of taking care of her. Here's what they said: "She seems to have soiled vent feathers all the all the time. None of my other hens have this. Maybe vent gleet? IDK, but she is full size and about 8-10lbs very pretty and healthy in every other way." I feel bad for this girl, the owner clearly isn't going to try to help her. What could be wrong?
