About 15 years ago wwe brought st run chickens and they were allllllll Roos. Meanest things I could not walk outside they would attack the kids, we PAID someone to come get them lol.
If the blueish chick is a roo will he be mean?
He may not be mean if he is your only one. I have a full grown barred rock rooster and he is as nice and gentle as can be, but the more you have they tend to get crochety lol
