I have 2 - 7 week old pullets and they are full time out in the coop. We decided to add 2 more so we now have 2- 2 week old chicks in the brooder. When would be a good time to integrate them? I was thinking of waiting til the 2 week olds were about 6 weeks old then putting them n at night like I've read about on here. My coops fully enclosed and they are not free ranging. Another question- should I add more space to my coop? I was thinking of making it a double decker. And adding a ramp. Or should I just make it a double decker and have 2 separate spaces for each pair with no ramp? Any info would be appreciated. Thanks!
