I have 21 chicks that are now 2 weeks old. They are in the process of fledging out (although one or two stragglers are still fluffy), and I have started the process of gradually moving the heat lamp a little further away every few days. Ultimately these guys are going to an outdoor coop, ideally by the time they are 6 (too early, too late?) weeks old. We live in Colorado where spring temps are highly unpredictable, so I don't want them to freeze to death or have a hard time adjusting. Any suggestions on the acclimation process? How old should I expect them to be when they are fledged enough to deal with temps in, say, the 20sor 30s? The outdoor coop has a sheltered area closed in with plywood for everything but the floor (wire) and in cold weather I plan to put a layer of straw on the floor (possibly under a piece of cardboard). Any and all suggestions welcome, as I am a poultry/quail newbie.
