Well done Saladin! I would also add: High tails, pinched tails, pearl eyes, and generally over refined and crow-headed birds.
The way I see it, is every strain or color or what have you I have seen, has to my eye many excellent strong points and some weak points as well. Of course when I cross strains I run the risk of getting a chick with all the bad points of both strains. I also run the "risk" of getting a chick with all the good points..
I'm thrilled personally to finally have multiple strains as well as a colors here on my yard, and I fully intend to cross them this season.
I think my final statement is that selection only works if the trait you want is there in the first place. If you want short beaks and multiple spurs, and your birds don't have them at all, you are never going to get them in any reasonable timeframe without crossing to another strain or breed that has the traits you want. The diversity has to be there in the first place to make selections from. Most of the folks who say never to cross strains have experience in breeds with very high degrees of perfection that need only minimal work on minor points. Most of the Cubalayas need a lot of work on many issues-I'm working on bringing the breed back up to the standard, not on perfecting minor details yet. So don't be afraid to cross strains!!
