We are new to chicken farming. Have three young girls and look to add four more next month. I have a problem right now. We have a coop and run setup with an extended optional run. They have been in doors and are ready to go out, but they hate the coop. I have been carrying them into the run everyday for the last couple of weeks and want to move them out permanentely. But they get indignant when we place them in the coop and bolt for the run. Have been trying to bribe them with a heat lamp, treats and even open window. But no luck. Any suggestions?
