I'll post pictures later, but one of my ameraucana hens, Penny, recently started limping. I thought it was because she propelled herself through the snow and hit the stairs but then recently, her toes have gone a white colour and started swelling. I don't think it's bumblefoot; she doesn't have sores or anything, though I'll have to look into it more closely. If you have any idea of what this could be, it'd be very helpful. Like I said, I'll post photos as soon as possible. I lost one my boys last winter to an injured leg and I don't want to lose my precious girl this winter, too. She was just born this Spring. Also, I think they've all been molting.
