I noticed these spots on my hens feet and my first thought was bumblefoot. I did do a search for pics to see if this is what she has but I was unable to find a pic of the early stages of bumblefoot. Her feet are not warm and the spots seem smooth instead of scabby (sp). Her roost is only about two feet high and she lands on pine shavings, so its a soft landing. Though they do free range and from what I've read she could have gotten a small injury that way. So I thought I better get some opinions. Is this the early onset of bumblefoot?
