My last batch of chicks is now 4 weeks old and I am really wanting some babies! However, I am in Pennsylvania and thinking this may be a bad idea. I have a mixed flock currently of 21 chicks between 3-4 months old, then I have 17 chicks that are 4 weeks old. The chicks were raised in a cage with the heating pad. By the time I move new chicks out, it'll be November and the new chicks will be 2 weeks old, and the other chicks will be 7 weeks old and 4-5 months old. I will have also given away some of the chicks that turn out to be male. This is my first winter with chickens so am I setting myself up for too much work by trying to keep peace between all of these ages and trying to raise chicks in the cold? Coop is 12x12x8, I use the deep litter method, there is a large amount of roost space, and everyone free ranges during the day. Tell me this is a bad idea? My finger is about to hit the "place order" button!
