I have a coop that has an upstairs and a downstairs- I have 4 birds and just bought 3 more. In order to integrate, they will be housed separately for awhile, however that means my current group will be up and my new group will be down. The "downstairs" is more open air, and although it does have roosts I will be making a little "house" to put inside for them to go in. This house is more than likely where they will stay at night (warmer) but will not have any roosts. Does anyone see this as a problem? The new birds are adults, fully feathered and probably used to roosting at night. Thanks for the input.
