20 week olf silkie with cross beak, pullet or cockerel

[HAPPYCHICKENLADY17]

i will post some pictures of graham cracker, is it he or she? doesnt crow yet, but the other day my 20 week old white silkie roos got into its coop and he tried to mount graham cracker....what is up with that, can a roos mount a roos???? so confused as to its gender, it is side by side with a little white frizzle bantam the same age,(im sure the little frizzle is a hen) they never leave eachothers side
