I have a hen that has a spot on her lower jaw, can't tell if it is an injury, or a pecked spot. Today I saw one of the other hens pecking her, so I removed the one with the bad spot and put her in a dog crate for a chance to heal and have some time alone without being chased around and bothered. But maybe I should have isolated the mean one who was pecking at her! Or would the others just have pecked her as well? Hopefully I can get her better, but then how will I ever reintroduce her back into the flock?
