About the only thing you can tell from a chick this age are whether the comb looks like it is probably correct and the number and placement of toes.
The bird needs 5 toes on each foot; no more, no less.
Crests come later; at this point there is no telling how well your chick will "crest up," or not. I see what looks like some middle toe feathering. If there it will likely fluff out. If not present it won't come in. But the outer toe feathering looks very nice and may well cover up a sparce middle toe.
Muff & beard looks ok. The good news is that the bird may well develop into an acceptable silkie; the bad news is that it will be months before you know.
Regardless of quality of the bird, it can be used for showmanship. Showmanship relies upon the child, not the bird. If there are faults or DQs, your daughter will need to know what they are, and be able to address how the bird should be. Your daughter's knowledge of chickens in general, the breed of her showmanship bird and that specific bird is what is judged. Also, how well she can handle the bird, and its condition.
