Is This Little Guy a Boy or Girl?

[Chickie Mamma]

Hello, its about 5 weeks old. I know its hard with Silkies, but any guesses would be appreciated. The last pic is my HUGE 3-4 week duckling. Does anyone know how long before we see a curl in his tail? I am hoping for a boy. His tail is definately not smooth or straight llike the ladies I have. He grew 3 times faster than the females I have. Is that any indication? Thanks for any guesses..

Here's ducky butt..

The silkie might be a roo . Its comb looks like its a little rasied but may be a female

The duck will grow its curl feather when its feathers come in although it way be the last feather to come out . But you will see it start to grow
