Keeping the girls safe from area predators, shade, and providing lots of space always keeps them happy! Plan on free-ranging them a bit each day? Otherwise provide a perch, tree stump, child's table, a bench, a dust-bath area, plastic chair, a doghouse, or a couple potted plants/dwarf trees, etc, as things for them to keep from getting bored. We found our first 4x6 penned 2 chickens so active that after a month we had to free-range them -- but with lots of places to hide/snooze during the day. So far in 51/2 yrs we haven't lost a hen to the Cooper's Hawks. Love your big green property! We're going into our 6th-yr State drought and there's fire season warnings in effect!
