I have 2 male buff orpington chicks I ordered from McMurray two weeks. Everytime I stick my hand in the brooder they always charge my hand pecking at it, one more so than the other. Is this a sign they're going to be aggressive roos if they're aggressive as chicks??? I've always had orps every since I started raising chickens & they're a lovely docile breed but these 2 little guys are pretty fiesty.
