How do I determine the gender of my polish chick?

A month or so ago we went to buy more hens and my little brother saw the adorableness of the poofy headed polish chicks they just happen to have at Tractor Supply. We ended up getting two of them as well as the hens I planned to purchase. Unfortunately, his dog didn't know he couldn't play with the chicks like he does with our other dogs and we lost one of the polish. But that is beside the point~ Now I have come to understand that I have no clue how to determine the sex of a polish chicken. With my other chicks I can easily tell by the growth of their comb and such. I have a photo of our polish but it is a little flighty so it isnt the best but is there anyone who can explain to me how I can differentiate gender with polish chicks?

A boy usually has a messy crown. A girl has a crown that’s neater. Look up a polish hen and rooster. You will see the difference.

Your polish appears to be a pullet. She is cute!

I was finally able to take better photos. My research was inconclusive. My little brother hopes it is a hen so it will have babies
