Hello! I am fairly new to this whole chicken business and am already obsessed! I started out with just a few buff orps and silkies for my backyard coop but now have 10 chickens (3 light brahmas, 5 buff orps, 2 silkies). Our coop is only a 12x4 ft space and I am wondering if these breeds can live happily together. Also, is this enough space for all of the chickens (all pullets)? I know that the rule of thumb is approx. 4sq. ft/chicken, but since the brahmas will be so large, I want to make sure I haven't overdone it with all of these chickens (not that I can imagine ever giving any away!). I'd really appreciate your comments! Thanks!
