I built this really large run for my first three chickens (10x10). 1 week later I added five more chickens to the flock and started building the coop. Once I had the underside of the coop fenced in I opened it to the chickens from inside the run. They were ecstatic to get in and enjoy the new space (4x8). So this was a very happy day. I couldn't wait to get the coop finished so that they could go in it to sleep. I got it done and opened to the run with a ramp that goes up to it and they refuse to go in. Once in a while Fog Horn will go in and check it out but he comes out almost immediately. When night fall comes all the chickens roost outside on the original roosts. They refuse to go in. Is there something that I can do to get them to at least go in to the coop at night? I am not wanting the hens to start laying eggs outside and I am afraid that they are going to do just that if I can't get them interested in the coop. Please any ideas would be greatly appreciated.
