hi all.. Still working on the coop/run and getting close now.. We've got everything enclosed but still need a door and sides on the coop.. So.. My next question is regarding the steepness of the ramp from the coop to the run.. Our coop is about 3.5 feet off the ground and once I figure in the deep litter method being used it may be higher.. Is there any issue with having a steep walk from the coop to the run for the birds? The length of the run from the front of the coop to the far side of the run is 8 feet.. Is having something along the lines of 5-6 feet long OK for them? I don't want to make it too steep..
