I have two 16 week pullets in a coop right now. Tomorrow I am having a new coop and two more 16 week pullets from the same place I got my original girls from 4 weeks ago. I will have two coops for a week, then I have a buyer for my old coop. I am wondering a few things. If I put the coops next to each other with the runs next to each other then the new birds will get to know the new coop and will they establish a pecking order that will just be disrupted and have to be reestablished again once I move the existing chickens into the new coop with the new chickens in the new coop? The old coop is smaller than the new one. What should I do?
