These are pictures of one of my girls. I am not sure what it is. Please advise. I only have three hens and no roosters. They have been like this for a few months and it doesn't appear to be getting better. They are very active and eat and drink well, no indication of any type of problem. They are good layers and no egg problems. Should I be doing anything? They all look the same and I have watched them and seen no pecking at each other. They are about eight months old. How do I post the pictures, I have them uploaded but still trying to figure out how to put them here.
