Great thread! We're working towards flock diversity. We've got 2 roosters over just under 20 hens. We've got a bantam rooster that has protected our flock from EVERYTHING (coyotes, hawks, foxes, you name it), and standard sized rooster. Our hens include production type hens, larger egg layers (like australorps), and a CornishX (Tyson truck chicken that fell out!), and a few bantams and mixes. We're looking to get a bunch of silkies, as we recently lost ours, for broodies, and a maybe a few Cornish (not X's, purebred) to breed Cornish X's. I'd also like to get some heat specific (thinking penedesencas/more leghorns/hamburgs/etc.) and cold hardy birds (maybe a buckeye) , just for flock dimension.
We've also been considering a meal worm farm to supplement their feed and free range, just in case, and especially in cold weather months.
