One of my Marans has lost her right foot, and I'm sure the left will be soon to follow. We had a severe cold snap here (temps to -35F) and she was the only one of my chickens who were effected. I feel bad for her, but she's eating and drinking well. The day I discovered that her foot fell off, I was a bit startled but not surprised. Both her feet had blackened completely, and seemed to be more of a hindrance to her as she roamed around the yard. The other chickens didn't bother her then, but now that she has such a different gait, the other hens go right after her. I've separated her into her own "apartment" with food and water, and she seems quite happy. I'll be moving her into our garage for the rest of the winter, and give her a private "yard" whenever the weather is nicer. Curious what others think about maintaining a chicken like this?
