Just curious, since the commercial broilers grow so big so fast and usually die from heart failure or their legs being able to support them, does anyone know how the commercial breeders keep them alive long enough for sexual maturity to breed them? I know that they can't mate naturally due to their size but wonder how they keep them alive long enough for artificial insemenation or egg laying age.
I know from personal experience that commercial meat strains of turkeys have the same problems. I bought some day poults from a commercial hatchery and kept two females and a tom. By the time the tom was 6 months old, he weighed about 50 lbs.! It became a struggle for him just to walk. It was more of a waddle than a walk and he had to eventually roost on the ground. When he was younger, he prefered to roost about 15 feet in a tree. One day he dropped dead of a heart attack while trying to run and never made it to 7 months. The hens lived long enough to lay a few eggs but soon died of a heart attack as well.
