Incredibly well said!
"In the wild" excess male birds, and also the females, are often eaten as chicks by other animals....and, yes, they are often eaten while they are screaming, some are crushed so quickly they cannot utter a sound. Eventually ALL the birds living in the wild will die, be it screaming at the teeth and claws of another creature or quietly of illness....never of old age, that's for sure. They are eaten before they can get to the death from old age.
Shutting the eyes and ears to the facts of food production in this world does not make it go away and the best one can do is to undertake their very own food production so as to insure it's done as humanely as possible. Eating eggs comes with a huge responsibility and one of those is being able to kill or recognize that killing is necessary in that species in order for you to have your morning eggs. If one is not killing their own spent hens or extra roosters they cannot very well criticize how others are doing it, as it has to be done no matter what....whether one abstains or is horrified about it or not, animals need a humane death if they are being kept by us humans.
Death is a fact of life and with maturity comes the realization of that. Don't like chicks getting ground up? Raise your own and kill the extra roosters to use for your own consumption. Roosters are a necessary byproduct of egg production and that cannot be avoided.
