I have 7 mixed 6 week old chicks. They are in a metal cattle drinking trough inside my house right now. When should they go outside? I was told now but our weather is supposed to be in the 30s with snow. They've only been outside once. I do have a chicken coop outside with 11 other hens and roosters. Should I put them outside in the coop now? I'm conserved with the weather and cold. Thanks for ur help.
