We have 7 chicks who are about 4 months old and we have 7 chicks who are about 2 months old. I want to put them together as I feel the younger ones are big enough....however I would like some input on how to do it. I have family and friends who have introduced new chickens at night by just putting them in the coop...and have done so very successfully, but only a couple at a time. So should I put them in together a couple at a time? Or all at once? And if I do it a few at a time, should I put the older ones in with the younger ones. Any advice, suggestions would be greatly appreciated!!!! Thanks!!!
