I have a raised coop and currently have ramps up to the pop doors. My birds don't even use the full length, they just hop up halfway from the side or fly out when they leave, so it seems like a bit of wasted space in my narrow runs. I removed the ramp entirely once, but then they didn't know what to do. I think the pop opening is too small for them to comfortably fly into. I know I've seen other ideas here... I just can't find them now. Pictures would be much appreciated!
