Hi, We live in eastern Oregon and have ended up raising chicks in the winter for the first time. I have 7 to 8-week-old basque and 2-1/2 month old polish, all fully feathered now. Currently, they are in brooders in the garage. The polish just have a 100 watt bulb and insulated pads over their brooder. The basque still have heat lamps. The temp in there has probably been around 60ish. I am wondering when I can transition each to ambient temperature. The coops they are moving into are not insulated but are fully enclosed and not subject to wind, etc. Any advice on when/how best to make the transition. It will be sub freezing here for the next 2 months at least. Thanks!
