Hello, I just got 6 chicks that are 2wks old (3 RI red, 3 Buff Orpington) I have read numerous threads and looked at tons of the coop pics on here. I'm working on their coop design for my husband to build. I'm looking on building a 6x5 coop with slated roof 2-3ft off ground with a 5x13 run (6ft of that run is under coop itself) and 2-3 nesting boxes on the outside for easy access to eggs. Is this enough room for them to be comfortable? Also any suggestions on how tall the coop itself should be? I am hoping to keep it no higher than my 6ft fence. Thanks.
