I am new to Backyard Chickens and I have had my chicks for exactly 1 month today. There are 3 Buff Orpingtons, 3 Black Australorps 6 Barred Rocks (5 hens 1 rooster)
My concern is regarding 1 of the Barred hens. She has black callus or wart like growths on both her feet. She is slow to feather and smaller than the rest of the flock.
From what I have read and seen, this doesn't appear to be bumblefoot. The growths are only on this hen and appear to be growing in size. Their coop has some pine but is mostly mostly hay. They have some buckets for dust bathing and pecking in dirt. Attaching pictures of foot and size comparison with another bird.
