We are new to the chicken world and have 6 seven week old hens. We have built them an amazing coop with an attached and fully enclosed run. However, the coop is raised to allow for more run space underneath, and we can't get the chickens to climb the ramp by themselves to go into the coop at night. We are having to put them in there each night. The chicks don't seem to mind being in the coop. They are just figuring out how to perch. We still have the red heating bulb in there, that comes on with a timer at night, hoping to lure them into their warm home. Any suggestions??
