I had chickens for a while and had to sell them because I wanted to free range and my poor little silkies and sebright mixes wouldn't survive in the the great outdoors (which they hated). So what is a good breed to free range? I am looking to get about 20 chickens. Egg layers. Color isn't important. They will be put back up at night (ideas on getting them trained to do this?) and VERY hardy in the winter and the heat. Ideas? Thank you!
