I thought they need rooster to fertilize the eggs so that they can be hatched into new chicks. Unless they have enough males or roosters to fertilize, else they gotta have some form of artificial fertilization inplace in the hatchery. After watching the clip where over 100K or more of male chicks are exterminated daily, and comparing it to the recent news where some animal rights group are lobbying for signatures to free the dolphins in RWS, I can't seem to strike a moral balance how could one life form deserve more attention than the other. Maybe one deserves to die horribly for a greater purpose to sustain mankind while the other does not deserve to be jailed in captivity just to amuse mankind. If that is the case, then justification is not how cruel and the extent of death but which one dies for a better cause from mankind's perspective. :(
