See that's not fair and I don't think it should be happening. People who know they have an aggressive rooster, who hatch eggs from him regardless, or even worse - give eggs to other people to hatch, who then have to deal with his aggressive progeny. There's no guarantee that a nice rooster won't have aggressive sons, as some of this is still random chance, but it's a lot more likely to get an aggressive son out of an already aggressive rooster, who has it in him to pass on, than to just have bad luck from a good rooster. So if the person giving away the eggs isn't paying attention, I guess the person receiving the eggs should keep this in mind and ask about the rooster they are coming from, before committing to hatch them
The friend in my example has given me eggs to hatch for her a couple of times, with the intention of giving them back to her once they feather out. She always asks if I want to keep them first, and tries to convince me to keep them, but I always say no because I know their dad is a jerk. One cockerel from last year's clutch was especially sweet and friendly - total lap chicken, so we thought maybe there was hope, but as soon as the hormones hit, he turned into a monster. I had to butcher him for her because she was always bleeding from some bite or another that he greeted her with. Roosters are already such a crapshoot. It makes no sense to tip the balance even farther against you by starting out from questionable stock...
