It is too young to tell gender, especially with Silkies. Silkies can be so difficult to sex that sometimes you don't know until they crow or lay an egg.
They are cute, but I agree, they look a little off compared to my Silkie chicks, one of them even has regular, barbed feathers (Silkies should have shredded feathers) and a single comb. But, they do bear a striking resemblance to my Sizzles!
Definitely too young to sex.
Thanks for the replies. I will take some pics of the parents, they came from a lady here in Vegas that raises show birds. These were "pet" grade that she gave my granddaughter because they didn't measure up.
