I introduced my chickens to the coop at there 6 week mark. In the coop is just a roosting plank. Outside the coop is there run where there food and water is. Well the chickens won't go into the coop when it gets dark. So every night for the last week I pick them up and put them into the coop. They will stay in there the entire night until the sun comes out then they will walk down there ramp and eat there food for the day. Also through out the day I will watch the chickens and they will walk up there ramp and go in there. So I don't know what to do. Last night was my test run to see if they will go in there by themselves. Which I know they can. They do it throughout the day. But they didn't go in. They sleep outside in the run. I'm worried because rainy season is starting. How do I break them of this habit
