I have two coops that are 8 x 10. One of them houses 16 silkies. The other right now is home to 8 little d'uccles and three big hens. I'd like to get some more big hens. How many could the second coop hold, if any? I turn each coop out every other day to free range, and I mean really free range. We live out on a ranch and the chickens can really roam. When I'm not gathering eggs to hatch I could let them all out everyday. Otherwise I keep the silkies away from the d'uccles so I don't get mutts. So......how many more pullets can I fit in the second coop?
