I'm wondering if she has an abscess of some sort. I'm no chicken expert, so I would wait until someone else answers. I am a critical care nurse though, and the drainage sounds like an abscess. I know this is gross, but what did it smell like?

When you go to Tractor Supply and purposely don't get a buggy, because you don't trust yourself. Then when you realize their baby chicks aren't there yet, you leave mad lol.
