well by the looks of your baby that you posted (btw--OMG ITS SOOO CUUUUTEE!!) if its a boy it'll try to strut & gobble (which will sound REALLY weird the first couple times it comes from its beak) the girls are courageous they eat more bugs than the males, they fly more often, pick through their feathers, are smaller than the males, more often have smaller snoods, caruncles, & wattles & when they get bigger they'll start laying eggs (of course).
hope i helped
