We adopted our little chicks from a friend so we don't know who's a boy and who's a girl. We decide long before getting them that we would not keep the boys (I'm not going to slaughter them so I don't know what we're going to do with them) Anyway, they are only 2 1/2 weeks old, but two of them are very aggressive. They chase the others around and charge us when we reach in the brooder. I was just wondering if they are establishing pecking order or are those aggressive little bugger really boys. Any insight?
