Congratulations, you support eugenics. Historically governments have forcefully sterilized all sorts of people because their children would suffer unacceptably by the government's standards.

Now please look into the history of eugenics and see what the policy you support has meant in practice.

Much like historical eugenics supporters, you are ignoring the outside factors that are causing someone's suffering in your judgment, blaming a factory farmed chicken's suffering on them being a "genetic freak" rather than on the people that lock them in cages shoulder to shoulder.

The descendents of chickens will produce so many eggs that they will start rotting near the nest and become a health threat, so they need assistance with getting enough protein and with removing the eggs before they rot. This is not a life of suffering, they only need a tiny bit of assistance to live as full life as any bird.

Chickens choose to make their nests in coops if they are built for them. Fences around a chicken yard are usually there to stop predators from murdering them and most chickens will not fly over them even if they can, as long as the fenced off area is large enough.

The same goes for dairy cows, who need assistance getting the milk out because they produce more milk than their calfs can drink. A farmer with a bucket may be approached by cows that want to relieve the pressure.

Some vegans consider honey to be provided with consent if the beekeeper is gentle enough. By the same standard, chicken eggs gotten when helping them clean their nest and milk gotten from cows whose udders would otherwise break would be vegan.

Of course without killing the males, a farmer probably can't saunter up to a cow and help them get the milk out quite as easily, but that's a skill issue.
