Hi Friends, I am brand new here and just starting to design my coop. I'm using the bottom story of my kids' play structure. It's 52" from floor to bottom-story ceiling. Is that enough headspace for a coop AND run space underneath? Maybe 30" tall coop and 20" run space? There will be additional 6ft+ tall run space, but I'm counting on that under-coop area as part of the minimum run space requirement to make 80 sq ft for 8 hens. They will spend most of their time in the coop/run. I will let them free range in the yard for a little bit each day, but I will have to be able to watch them closely. We have hawks. Thanks in advance for your help!
