Crow heads is a serious problem in the breed. Really it's a general fault for most breeds, it tends to indicate weaker, unthrifty, poor producing birds. It seems to show up most, or first, in the females, as the males will naturally have a heavier, shorter, skull and beak anyway. This is a major issue to me personally, because crow headed birds are not as functional, and it really isn't what the breed should be anyway, orientals should have nice, short, heavy heads and beaks. If you look at the Schilling illustration of the cubalaya hen, you can see just how short the ideal beak should be. I decided that this year, this would be the number one thing I'd cull against. I originally tried picking them out at hatch, but, it's hard to do. I can pick them out for sure by 8-10 weeks though. It helps to have a comparison, I use a Ko shamo as my "good example", and a Leghorn, or a Polish, as my "bad" example, i.e., I hold up the cuba and compare it to the other 2 breeds, the ones that look more like a Leghorn head get culled, the ones that are closer to a Ko get kept. I also did make a big point to get a new cockerel with a good head and beak, and to put together matings I thought would produce some nice chicks. Some matings have given me bad results, the blacks, whites, spangles, mottles, produce 75% horrible crow headed chicks, and the 25% of nice ones are not great, but acceptable. My wheaten matings have been much better, maybe 80% have good heads and beaks, with maybe 25% having superb heads. High tails are a bad issue as well since they are a disqualification. !!!
