Castrating is rarely done successfully, personally I wouldn't want put any of my roosters in that position. It's really stressful for them, a large percentage of the chicks would die. I'm not sure if he would mount the hens. I do know the crow factor
would go down a little bit, the rooster would crow less and the crows would be somewhat lower in volume, but I don't think it's worth the stress it causes to the cock. My Silver Laced Wyandotte/Sumatra rooster was given to us by our vet that had castrated it himself. Badger is as healthy as can be, so it might just depend on the vet or the strength of the chick. You can get a vet to do it, but there are only a few vets around that would be able to do it, and the fee is $200-$300 dollars. There are do-it yourself kits, but that's really tricky and most likely the cock will die.
I don't see anything wrong with eating fertilized eggs. I've never cracked open an egg and found a half-developed chick inside. I keep 10 roosters in my flock, and I'm sure at least some of the eggs I eat are fertilized, and I don't taste a difference in fertile eggs and unfertilized eggs. Anyways, eggs need to be incubated at a certain temperature in order to hatch.
If you are worried about the crow factor, some roosters will crow less than others. I really like the crow of my Silver Lakenvelder and Basque. Their crow is low-pitched, and not too loud, and they do it rarely, and that makes them more tolerable than the rest... If you were to get a rooster with neighbors around, I wouldn't recommend a bantam, since their crows are high-pitched, loud, shrill, and more likely to annoy your neighbors than the crow of standard-sized rooster.
Aside from fertile eggs and loud crows, having a rooster will mean that your hens are safe about 98% of the time. A rooster is known to fight to death for his hens, and I can declare that true, that's what my Silver Campine rooster did. So definitely any rooster, either castrated or not, will protect his flock. And trust me, Badger (the castrated cock) is the most protective rooster in my whole flock.
Hope this information was helpful!
