I also just finished reading all 15 pages and am so grateful I found this thread! Our 14 chicks came this week and are in our brooder in the shop. We are starting this weekend on our coop and this was one of the areas where I wasn't sure what I was going to do. Trish, you have answered all my questions! Thank you so much! We are building a 10'x10' coop with 2'x10' of it used for storage. I already know what wall I'll be using your system on. My shelf will be a little wider to incorporate two parallel roosts. Thanks!
