How high can a chicken jump/"fly" The coop idea I have in my mind is to turn a corner of the garage into a coop, with the run on the outside of tha garage. I don't know if I want to make the wall do all the way to up to celing if I don't need to....do I need to? Do you think I should make solid walls or wire walls? And why? should the door open into the coop? Does this become a issue if I used the deep litter method? Thank you.
