I've seen all the threads on this one and tried what was recommended. We've blocked off the boxes at night, but then they "roost" on the floor - all snuggled up together. They're adults (2 years old or older), and I'm not sure what they did before we got them (from a farm). Interestingly, they are all (or almost all) on the roosts in the morning. There is a window (glass) up high that they look out and see us coming to let them out. It's not really cold yet (40 degrees at night) but I'm wondering if this is okay? or if they're maybe moving during the night to the roosting bars?
