breed and gender (pic Heavy)

I hatched it from an egg I got from a Poultry show for free. Someone had a carton of eggs they said they collected during the week from there birds and were ganna toss the eggs since they were prob not fertile so i asked if i could take them and this is the only on that hatched. Im thinking its a Buff Brahma Bantam. Im I right? and is it Pure Breed? And what gender?

 

the show was in july, hatched in the 2nd week in August sooo its about a month old

 

ok good lol im hoping for pullet.
