My girls went from a 8X10 inside space to a 10X24 with an additional 6X10 space off to one side where the roosts are at- They are so happy with their new digs- except I had to physically place them each on the roosts tonight..they were a bit confused about where their beds had gone. Their outside run is 10X20, plus they get to free range on our 3 acres every evening... I have 14 hens, 3 barred rock pullet chicks, and I am expecting a cackle hatchery surprise in a couple of weeks-
