This year I want to hatch a few of different breeds. I did some reading and found a few different articles that tout game birds as being the most broody and way better than any incubator. I already have 2 barred rocks , 2 speckled sussex, 2 marans, and 2 Buff orpingtons. I mention the other breed because I'm looking for a breed that can be housed with these other breeds that are pretty placid. Also I live at 7000ft so I need a breed that can handle winter nights that regularly get to 12f. So I'm looking for advice on which game breeds would fit the bill.
