I cut my coop door about 14 inches high. I had it covered with chicken wire until the fencing was done. Now the chickens don't want to go outside! I tried luring them out with apples, which they love, but they only venture a foot or so out on the five foot long ramp, which, due to the coop being on piers is about 2 1/2 ft. off the ground. There are Welsummers and Marans. The door is about shoulder height for the Marans. Should I make the door opening taller, or just let them stoop? Should I lock the birds outdoors for a while? The weather is 50 at night, and 70s during the day. Thank you.
