We have 4 Black Marans, 3 Barred Rocks, and 1 RIR, and we were thinking of breeding for more egglayers. It is cool where I live, most of the year and doesn't really get above 80. I also have younger children and would like a roo that I could feel comfortable having the kids around. If I bred a Cochin roo with my Maran, could I get a cool hardy dependable egglayer from the resulting hens? Or is that just wishful thinking? Also, what about the BR's and RIR with a Cochin roo, anyone have any experience with these mixed breeds?
