Book excerpt: Cockfighting has become a very difficult sport to compete, and there is a great need for cockers and breeders to produce the best game birds that can win battles. There is no need to settle for anything less and everyone who loves cockfighting or "sabong" should know what it takes to win and be consistent with it. But there are those who still have no idea what constitutes a suitable game bird for modern cockfighting, which goes back to how a brood cock and a brood hen come together. And while most of us could easily judge game birds by their outward appearance, it is not as important as the blood, brain, and spirit inside, nor is all good game birds exactly the same. But we can always try, to any extent or degree, to recognize the principles of construction that should guide us in the right direction. Our effort has been to highlight through this book the basic and most important knowledge that can be used as a reference on how to raise, breed, and condition game birds, as well as cite common problems every cocker and breeder can find from the shell to the pit and how to overcome them.
