Sylverfly, your bird is 100% male. Anyone who tells you it is a hen is either pulling your leg or doesn't know how to sex a turkey.
At this age, all the plumage characteristics of a tom are evident. The dark barring on the breast, wing coverts and sides,and the pronounced snood and carruncles..... all tom. Get him a girl friend or two and you'll be in the turkey business in no time. And yes, he will be fertile his first spring.
