Where we live is all hills. I was looking today where we could put a coop and run and there is no flat ground! I know the coop will need to be level and can deal with that, fencing etc, but I was wondering is it okay to have the run on a slope? Will the chickens not bother going down it and therefore making it bigger downhill is a waste of time? Or will they go down the bottom and not be able to/want to get back up? Everywhere I see has chickens on flat land.
