There are definitely more aggressive birds; I would say breeds, but it's more like certain strains. The two Jap roos I have from two different places are both really sweet, but I keep hearing how aggressive they are for others. All of our Mille Fluer roos have been terrible, unlike the rest. They are like attack robots. They were held often, like all the other chicks, hand fed, and still attack. They even attack when there is a fence between, and when they have a broken leg. We got rid of our nasty Sebrite roo for this reason. We have small children, and there is a possibility of injury, including blindness from flogging roos. Be careful with a chicken of any size that pecks eyes!
I doubt your chick is going to end up a nice bird, but it may stop pecking so much once the pecking order is established. I wouldn't risk it myself, since this one is pecking the eyes. I've never had one do that.
Blue-Kote works! But, not so close to the eyes.
