So the white one likes to take on my 70 lb boxer. She fluffs up and jumpes at the dog with her claws bared. The barred rock looking one is extremely timid and won't even forage far from the coop even when the other two are gone. The black one, has big tail feathers and started growing a wattle and comb before the barred rock but the growth just stopped. They are about 4 mo. old. Sooooo...what do you think?
