Your quail will go down that ramp but will probably not go back up it, my quail were a little retarded when it came to a ramp. Someone on here suggested steps because they like to hop. I did that and they used it all the time. Your bigger issue is going to be getting them to lay up top. They will go to ground to lay before they go in the coop. you could how ever put some supports that are level with the door to the coop and just keep them off the ground. You'll lose the space below but it will keep them from laying eggs down below. Quail are a little stupid, more so coturnix unless they are broody.
