I think it's natural for them to be frightened if they feel they are trapped. If that's the only time he does it and you know he will, then I'd say he's OK.
Of course, my only roo was an Ameraucana, and he wasn't really mean, but he would come after me sometimes. A predator got him earlier this year and I've been very happy without a roo since. Got lucky and none of the chicks I bought in July were roos - all pullets!
