My Orpington is under two years old and has been suffering from feather loss, weight loss and laying issues.She hasn't laid an egg since July16. I have other posts on her: https://www.backyardchickens.com/t/871508/feather-loss-and-red-skin https://www.backyardchickens.com/t/...loss-laying-issues-broken-egg-etc-shes-a-mess She is doing better but the scab she had on her keel has turned into a fleshy black growth. It does not seem to be internal and quite frankly, looks like a piece of dog poo stuck on her stomach (it's not). I soaked her but it didn't come off. Should I try to remove it? Is this a tumor? Should I be concerned?
