Does my small hutch need a slope to the design? Most of the coops I've seen have a sloped roof... It would obviously be easier to not have to make one, so I'm guessing there is a functional reason for the slope... Is it important? Do I need to build it sloped? If it makes a difference, we are only going to be housing 2, 3 max. Coop will be roughly 4x2, with the attached run 8x4 (side note - is that big enough?) thanks again for your help!
