Hi. I got baby chicks this November and they are currently residing in our "Michigan" basement while growing. THey are 7 weeks old and are at about 55 degrees right now. I was wondering what age I can transition them to the coop with the older hens. I have a porch room i can use to acclimate them, and am hoping to catch a week or so of mid-winter thaw, but don't know if that would be long enough for them to acclimate to Michigan in the winter. Any ideas?
