I have a mixed flock of 6 (barred rocks, buff orp, EE, and Isa Browns) with one EE rooster right now. Chicken math is creeping up and I'm thinking about raising Dark Cornish's for meat - but economically, I think it makes more sense to have a mating pair and hatch my own eggs in the future. How the heck do you keep a mixed flock, and separate the mating pair, and know which eggs you're supposed to collect to hatch?! I would love for all my chickens to free range together --- will they go into their own separated coops at night? Any experience with this out there? Is it even possible? I'm thinking I'd have to get rid of my EE rooster and only have a Dark Cornish Roo?
