Neighbor of mine needed to get rid of his 12 hens asked me if I wanted them..said sure why not. So as of right now I have all 12 full grown hens in a large dog cage sitting in my coop. Now I let my birds free range during the day and they roost in the coop at night. So my question is when can I let the new comers out and know they will be safe and return to the coop at night? It's only been one night but it's already getting cramped with all 12 in the dog cage.
