My babies are a little over 4 weeks old now. They have been gradually spending longer amounts of time outside in the run. Well, now they don't want to come back inside at all!! But, they have no night-time accomodations yet. The run will be predator-proof once i finish attaching the top, but still don't have a coop yet. I am feverishly working on a "halfway house" for them until I can get the large coop finished and moved. I feel so bad to have to force them inside every night, when all they want is to be outside!!
