To me, at first glance, it looks like a to, but there is no way to tell for sure at this age. If it is still small there is a test that my mother suggested. If you loosely hold your finger around his neck and lift slightly--BE SUPER CAREFUL NOT TO HOLD HIS NECK YOU ARE ONLY LIFTING UP BY BENEATH THE JAW-- if the legs droop it is a boy if the chick kicks and pulls the legs up its a girl. I don't particularly like this test but it is a pretty surefire way to tell. If you find it as unnerving as I do, you can just wait a little while longer to see what it look like in a while.
