Hello and welcome to BYC! Glad you joined.
It's way too young to determine gender. Wait until it's 6 weeks old and then post new pictures in the Breed and Gender Forum.
Cute chick! It's pretty early to know yet, however judging from the primary wing development it could be a female. In another month, you should be able to tell, and you then might start a thread in our What Breed and Gender forums for positive ID... https://www.backyardchickens.com/forums/what-breed-or-gender-is-this.15/
