Yazzo's advice worked well, mydog8it, when we had issues with our rooster. We are vegetarians as well and couldn't kill our friend LeMerde. After much debating, we realized that with such an aggressive rooster (he was my sweetest and then turned very antagonistic, and without warning every time) and with my disability (muscular dystrophy - lack of balance so I will fall down whilst running up the hill from the attack rooster, and paranoia from the vulnerability of my neuropathic limbs) we decided it wasn't worth it. Unfortunately we did straight-run chicks, so we had to give up about four roosters.
A few months after we re-homed LeMerde the attacker, my Olive Egger hen turned into a rooster (grr!) and became even meaner than the first. I found a home for him as well. If you can handle wearing thick clothing and being on guard all the time, I'd keep your rooster, especially if your girls are going to be outside and vulnerable to predators. But if he's attacked once, he'll do it again if you let your guard down.
My girls have been so much more docile without a rooster, by the way. I loved how beautiful my roosters were and I loved the crowing and protecting of the girls, but a peaceful flock was our top priority so it wasn't worth it for our particular household. Good luck!
