We have 3 lilac bantam, these are our first chickens. as you cant see Chick 1 and 2 are bigger than Chick 3 and are always squaring up to each other, where Chick 3 is very placid, I know they are still young, can anyone help sexibg them? Please

These look like Blue-laced Red Wyandotte bantams to me. I have no idea what a "lilac bantam is". Additionally sparring isn't an indication of gender. Chicks will establish a hierarchy or pecking order fairly early. However, I would guess that Chick 1 and Chick 2 are probably cockerels. Chick 3 could be a pullet, or it could be a cockerel that isn't developing as quickly.
