Well, this is the starter coop. I am building another quite like it as you read. Yes, I built this one. total dimensions are, front to back 48"; side to side 65" Total avail. floor space is 42 5/8 " X 60". Total floor space is 18 sq. ft. i.e., good for 4 to 6 standard size mature birds. I prefer giving 4 sq. ft. per bird myself, rather than 3 (I've even read 2.5 is ok; but not for this monk) Range is movable from front to back of coop for fresh forage ev. 2 wks. Chicken tractor is in foreground; it is 8ft. X 4ft. Tractor is also just the 'first generation' model. Also, the main coop is portable (with the effort of 4 people and some hoofing.) My next is going to be truly portable (for two!) I hope I won't offend you by saying, "God bless you" ps I'll post more pictures, either in this thread, or I'll create another like it.
