I have two 7 week old pullets that I will have to introduce to my flock of one laying hen who is less than a year old. They are separated now but can see and interact with each other through wire. There is interest on both sides of the fence. My question is should I try putting the two 7 week old pullets in with the one older hen is it easier because there is no other competition with other laying hens? Should I introduce the pullets in to coop at night? Any advice is welcome I'm still new to this.
