I must have 2 of the types. "Fanny", now 2 1/2, has a small, single comb. Her 7 sisters, now nine months old, have really big single combs, that vary in size. It seems like the most aggressive sisters have the largest combs. What gives? Are my birds all mixed up? I got Fanny (and her 5 brothers) at an auction, and they came as a clutch in a shoebox. I bought her sisters at a farm supply store that orders through McMurrary hatcheries. None of them them are very dark, and the 3 brothers who, ahem, went to freezer camp, had only dark green tail feathers, no dark saddle feathers.
BTW, Fanny isn't afraid of my dog, Rose--she went after her last night in the new digs--the barn stall, for the winter housing. But the others run from her. Fanny is definitely bottom of Their pecking order. I'm confused...anybody!?!?!?
