Love the additions to the coop. The fox cut out is amazing! WOW!! Impressive! Okay, so I really love the water nipple idea, but how do you keep it from freezing in the winter? All of my waterers froze last night. I'm going to break out the cookie tin heaters for under them... but what do you do for the nipples??? Looks like you're making that coop easier to work with, and I love those ideas.
