I have owned chickens on and off for almost 13 years now, but until now have never built my own coop...my dad has always built what we referred to as a "ramshackle coop" out of what ever was laying around the yard, or we have once in a while used an empty rabbit hutch for a pair of them. I am now being faced with the semi-daunting task of building my own coop and I am wondering... 1~What kind of materials would best suit? 2~What is the best way to raise the coop off the ground? I've been told bricks, cinder blocks and 4x4s...I just don't see how the coop wouldn't slid off of bricks/cinder blocks, and the whole point of raising it off the ground is to prevent rot getting into the wood so I don't quite see how 4x4s would help... 3~How many Square feet of coop do I need? (This will NEVER house more than 5 birds but birds may be standard/bantam/mixed) 4~How many Square feet of "yard" do they need? 5~Is it better to build the "yard" walls out of stretched wire or framed panels? 6~How big does my pop-door need to be? (and for that mater why is it called a pop-door?) 7~Do I need to build separate nests for each bird or will they share? 8~How big should a nest box be? 9~In areas where the winter(and spring/fall nights) temps can reach Zero Degrees (or lower) is a round or flat roost better? I'm sure i will come up with more questions as i work my way in and out of panic spells between now and the time the thing is finished and the birds are moved in.
