I have two 6 weeks old Lavender Orpingtons. One has a strange neck tuft that fluffs up, is very cocky, will peck your hand when you reach in the brooder, watches everything, and stares down our dog. He or she is sweet once out of the brooder though. The other is very calm and sweet all the time. Both are the biggest out of our 16 chicks which include Leghorns, Buff Orpingtons, Wyandottes, Partridge Rock, Speckled Sussex, Fayoumis, and Blue Ameraucana. The first picture is the cocky bird and the second is the sweet one. Do you think one is a cockerel? Both? Neither? Thanks!
