My family owns about 14 acres. We plan on getting 50 Freedom Rangers this spring, plus we plan on having around 50 layers. We want to have 2 movable coops (one for the meaties and one for the egg hens) to house our chickens so we can move them around our land so one area doesnt get over saturated with chicken poop. I have seen lots of picture, but very few actual building plans online, for egg mobiles. Does anyone have any building plans for these types of coops? I live in upstate NY so the coops would have to be closed up in the winter. I have seen lots of egg mobiles that are mostly screened in and only used in the summer. I would need one that would be good year round, at least for the egg layer, I dont plan on having meat birds in the winter. I have a book with animal housing plans that has a good portable brooder on skids, but nothing for a large amount of adult chickens. Has anyone else built one of these large mobile chicken coops, and if so can you give me some advice? Thank You.
