I live in central Wisconsin where as some of you know it can get VERY cold here at times. I currently raise frizzles and Millie Fleur D'Uccles and they are doing great but I was also interested in raising Seramas, however, I have read that they do not tolerate cold weather at all. Would it be wise or safe for the chickens for me to try to raise them here? Would I have to bring them into my house in the winter? During the summer it is very nice here, but the winters SUCK!! Any advice you can offer me would be very welcome. Thank you in advance!!
