I have six, 7 week old chicks who have been out in a coop with an attached run for two weeks. I let them out of the coop early in the morning and I put them back in just before dark each evening. They do not want to go back into the coop and I have to pick up each one and put them in. I leave the coop door open all day and they will climb the ramp and go in and out on their own during the day. Is there something I should be doing to train them to go in the coop at night?
