hi. I just had a question about some chicks I just got from TSC. I went in to get a couple silkies they had from the bantam bin. They only had four and since you have to buy six I ended up with two mystery chicks. I've established one is a golden seabright and one is a porcelain d'uccle. I live in Northeast Pennsylvania and understand these two breeds are not cold tolerant. Is it possible for them to survive here? It got quite cold last winter and I would hate for them to freeze to death this coming winter. Thanks for any help.
