Well it sounds like you have quite the chicken farm. My suggestion is to keep them safe from the wild critters. Coons, Hawks and Eagles not to mention Skunks love chickens. An enclosed yard and coop will do you best. I buried wire underground so the critters can't dig in then you cover the top...
I'm excited to join your group, looking forward to learning more about my chickens. I also have a bunch of Roosters I want to give away so if anyone knows someone please send them my way. I am also looking for some Maran laying hens of chicks
