I have a flock of 12 peeps and am finalizing my plans so dh can build the coop while they are living in the brooder. We live in the country, high predator potential. A gazillion hawks everywhere, some eagles, have seen fox, assume that there are raccoons around . I live in southeast Virginia, mild winters, scorching summers, wet autumn and spring. I have a mobile run (tractor like but no coop on it, basically a long cage with open bottom and shaded area at one end. They will be taken out in this as often as possible to free-range and bug control. For the coop I plan a raised building, perhaps 30 inches off the ground. attached will be a run. The wire for the run will be hardware mesh, 1/2 inch square. I have some animal pen fencing that I think has a mesh of 1x2". I know this is too small for the outside, but I'm thinking of putting it as a "floor" to the run to stop digging predators. Then sand/dirt could go over it. If the 1x2 is too large, I could run two pieces at 90' to make the mesh overlap and thus be smaller. I have to keep costs down and I have several large portions of this stuff that came with the house. Other "found" items that I think will come in handy are the very large metal arches that came from a trampoline safety fence. I think they will make the framework for the attached run on the coop. A question about that: does the top of the run need to be covered in hardware cloth too, or would poultry wire be ok. I think it is to deter hawks only... or will raccoons and other things climb up the wire walls and tear through a chicken wire "roof"? Size-wise I am thinking an 8x8 coop with an attached 8x10 run. This would be open to them all the time, even days they don't go out in their bug-mobile. Am I missing anything? I have read many posts on here with ideas about roosts, nesting boxes, feed and water placement, etc. Oh, one thing I would like suggestions for, ventilation in the coop. Sometimes in the summer here, it can stay in the 90's almost all night, so in the summer, heat is a problem. However, I would need to make it possible to be contained in the winter. We don't have much snow or freezing usually, but every few years we get a colder winter. would vents in the eves and an open door be ok or would you do actual windows with shutters? thanks.
