I have 3 pair of bantams and I'm making a new coop for them that has 3 sections each section will be 4ft width by 8 ft long with a small house attach to it about 2ft off ground the height of coop be about 7 to 8 foot, and have a slope going down towards the back at about 6ft high so water will run off roof each sections roof be cover in metal roofing, this coop will be built safe from predators including snakes. I have 2 old english game pair that are 1 hen & 1 roo, & then i have a silkie trio pair of 2 hens & 1 roo. So my question is will each section i describe be big enough for these 3 pairs? Thanks
