I have 6 hens and a rooster, who overnight in a 4' x 8'coop, and spend the whole day outside, in an area roughly 2000 square feet, mostly shaded. They do pretty good as far as I can tell, and the egg yield is about 60% a day. They go into the coop around dusk. One time, though, the wind blew the coop door shut, and they roosted on top of a small abandoned doghouse next to the coop until I picked the hens up one by one and put them inside. I was not planning to tangle with Enrique, who went of his own accord as soon as the girls were inside. My only question is whether they have anything left to scratch for on the ground all day (though I give them ample layer feed)- the only vegetation is trees and shrubs; they ate up nearly all the leafy annuals ages ago. There is a layer of dead leaves over most of the area; I just don't know what kind of bug population is there. Predators are not a problem, knock on wood, because we have 2 outside dogs. There is the occasional egg-stealin' rat snake; that's about it.
