We brought our baby chicks outside yesterday. They are 6 weeks old. We built a nice chicken coop for them. Inside they have nice nesting boxes and also a large tree branch to roost on. They haven't ventured outside yet. The chicken coop is built on stilts, so there is a ramp for them to use. How can I get them to visit outside? They will love it. It is fenced all around and has plenty of room to scratch.
