To tell you how I got to where I am today, is rather lengthy. But here is my scenario. I have two coops. One larger coop and one smaller coop. In the smaller coop I raised baby chicks in, until they reached the size of the adults I already had. The two groups are now integrated during the day, and the younger ones should start laying eggs soon. I would like to make the smaller coop a 'nesting coop' and the larger coop the 'roosting coop'. This is not the norm, and I'm not sure that it's acceptable. Do they have to be under the same roof, nesting boxes and roosting bars? As longs as they are out of the weather, does it matter? Please help.
