We are almost done constructing our first coop. Due to prevailing winds, we changed our plan and decided to have the pop hole and ramp come out the bottom of the coop instead of from one of the walls to minimize draft. We have never had chickens and my husband and I have had much debate over the ramp and if it is (or even could be) too steep. When we lower the angle of the ramp to make the grade more gradual, then they have less headroom to get in and out of the coop. Is there a magic angle? We're thinking at this point we will just leave it and if the chickens are having trouble negotiating it we will adjust it. I'm just curious from others experience what sort of angle and head clearance the chickens like to navigate the ramp through the pop hole.
