I have 17 assorted chicks that are 1 month old. They are in the coop but I have not let them out into the run. They have been in the coop for about 2 1/2 weeks now. When I let them out how do I entice them to go back into the coop at the end of the day? Will they go back in where they feel secure to roost? I hate to think that my husband and I will have to chase them all over the run to get them back in.
