I got a sultan chicken from meyer they said they were cold hardy now I am learning that's not the case. She doesn't have much down and it gets -25 here in the winter. My run is wraped in plastic during the winter the so the ground stays dry. Their house is well ventilated on top and this year we added more chickens so it should be warmer. I do have a EE bantam that made it just fine last year but she has lots of down and no feather feet. Anyone else kept a sultan under these conditions?
