We got our first chickens a couple weeks ago. 3 pullets that are currently 3.5-4mo old. As soon as our big coop is complete (another 1-2 weekends and it will be ready) we want to add 3-4 more chickens. We will get them from the same place as our first ones and they will be roughly the same age, 3-4mo old. Will I still need to do a slow integration of the new ones? They will all move into the new coop at the same time, will all be roughly the same age, and we’ll have only had the original 3 about a month at that time. Can we put them all in together right away and let them work it out, or should we go ahead and separate the new ones at first?
