I have 5 roosters, 5 hens, and 4 baby chicks right now. All are separated. I am having a coop and yard fixed for them. I would like to have it divided in half. How big do you think the run needs to be and also the coop(s) if I have 2? Can I separate the roosters from the rest, so I don't have to cull them? I've tried Craigslist to find a home for the roosters, with no luck. I'm new to all this, so please bear with me. Thanks!
