We currently have a ark style coop and will be upgrading to a 6'x6' shed style coop in the spring for our 4 hens (1 BO, 1 BPR, 2 EE). What feature do you like most about your coop, and why? I have seen some neat ideas from a drain installed in the bottom of the coop to an adjustable floor vent used near the "attic" area. If my DH is going to invest time building the coop, I want it to be as awesome as possible!
