Believe it or not these are not the first lines of terrible jokes, but real scientific questions with real living answers. Hybrid animals are the offspring produced when two animals of closely related â but different â species breed.The young produced will usually not be fertile, and so hybrid species are not normally seen in the wild. In order for more of these hybrid animals to exist the original two species must be cross-bred again.elieve it or not these are not the first lines of terrible jokes, but real scientific questions with real living answers.

Gamebird hybrids are the result of crossing species of game birds, including ducks, with each other and with domestic poultry. These hybrid species may occur both naturally or though the intervention of man.omestic fowl can be crossed, and produce fertile offspring, with silver pheasants, red junglefowl and green jungle fowl. They have also produced hybrids with peafowl, chachalacas, capricale, grouse, quail, curassows, pheasants and guans.
