we have a chicken tractor for our chicks. they go in the run every night about dusk, but then my husband and i have to fight with them to get them to go into the coop. this has been every night for the past two weeks. they just hunker down and go to sleep right by the door to the coop. when we shut them in finally they just peep and whine at the door. so question is, how do i get my little guys to go into the COOP at night? i can't be fighting with them every night to get them inside, its absurd. any suggestions are much appreciated! thanks.
