When I first saw the idea, I fell in love with the idea of a cattle panel coop as winter shelter for the chickens However, there are two problems with the mobile model of the coop that I have seen replicated so many times. I'm a tall person (6'1"). In order to make a coop big enough to house all our birds We would either need to make it 50ft long, do 3-4 of them or have the span so wide that I can't get in easily. This is shown well in this diagram. In the late winter, early spring we have some real wagon tipper winds whip through our hollow (valley). And I would be afraid that one of these coops would go flying in that sort of gale. So I started thinking about more permanent versions of a cattle panel coop and came up with this idea. It is a cinder block foundation (mortared together) on concrete footers. On top of the cinderblock will be wood nesting boxes and feeding areas that we can access outside the coop. NOTE, the top of the outside half of the nest box/feeding areas that is overhanging the block foundation is supposed to be sloped down and will have roofing material on it (the free CAD software I found didn't do any lines other than horizontal and vertical). The roof will be cattle panels over a 14 ft span covered with greenhouse plastic over the winter. The reason for this is because I want my chickens to be able to get natural sunlight if we need to leave them in during particularly bad weather. I also want to make half of the coop into 4 breeder pens. This way my breeder birds will stay warm, dry and most of all CLEAN. The cinder block foundation will have 3 interior walls that work to divide the coop as well as anchor points for the roof support trusses and ridgepole. The support posts will be cemented into the cinder block so they can't blow away. Is there anything in this design that I am not considering? Are the designs clear enough? Thanks in advance!
