Here are examples of my white silkies. I had to take video instead of photos b/c I didn't have anyone to hold the bird while I held up the legs. Both chickens are 7.5 weeks old.
Here is my male. I know he's male b/c he tries to crow. As you can see he has a large spur bump (as do my other 2 males) and a developed comb. He has a larger body than the females and was slower to feather. His head fluff also sticks up, the females have head fluff that is flatter. (Please excuse his dirty face, he was catching bugs right before the video was taken).

Here's my female. Smaller body, no comb development, flat legs with no spur bumps, flat head fluff.
