yea i'd put 2 really wide doors on the back. they wouldn't have to be very tall just tall enough so you can get a rake or shovel in to work. since your coop is 14 ft long i'd do 5-6 ft wide doors. put the hinges near the base of your coop and make them idk 2 1/2-3 ft tall. also forgot to say the coop i seen with the chicken door in the bottom put hinges on the ramp and had string tied to the front so when you pulled the string up the ramp acts like a door to close it off hope that makes since.
