Best coop for backyard chickens
There is no "best" chicken coop. When housing chickens you simply need a place that the chickens can get away from the weather, the don't like wind and rain. The housing system must be able to keep predators out, both wild animals and domestic dogs, the birds prefer to sleep on roosts that are off the ground by at least a couple of feet or more, depending on the types of chickens, and a couple of nests that provide a safe and comfortable place for the hens to lay eggs.
For many ideas, simply google "chicken coops" or some other appropriate terminology and you will get many suggestions from small producers that have many good ideas for housing chickens.
