Hi every one. New guy here. This is my 5th week to owning chickens. I have 6 little ladies that have grown up so quick. Its time to get them out of the house and into a coop. I have been gathering supplies for a couple months, from random demo and contract side jobs. My plan is to build a 4ftx4ftx4ft box on 2ft high stilts. It will have an attached 5ftlong 6ft high 4ft wide run to the right of it plus the space under the house, fully screened in. My questions are Should I have a roof over part of the run or is the house and the underside of the house enough shade? As far as ventalation we see high heat in the summer I plan to install a whorley bird turbine on the top and bird block holes in the tops of the roof at the high side of the roof pitch. Is more air movement nessecary? How big should there door opening be? How big should the nesting boxes be? I always have aluminum chaffing trays around I was woundering if anyone uses them to line the bottom of the nesting box. Just lift out and dump to clean the nest? As far as the birds pooping will they continue to poop where they sleep or will they go out side or just the main floor of the house. I think those are my biggest questions for now. Sorry if I am asking stupid questions. I have been reading and lurking for about 2 months now but still very new.
