Fleas on baby chicken

[Newchikkyx]

Hi i am looking for some help with my baby chicken he was kicked out from nest due to a wing injury and i am now taking care of him inside. My question is can i use flea powder on the babies? He is about 2 weeks old starting to devolop his wing feathers.
Thankyou in advance!
