I hunt them like crazy too, also raise rios, merriams, and had osceolas, easterns are illegal in Georgia to have because they are our native bird, is the only reason I dont have them.
As for your original question
at 7 weeks old, there's now way to know the sex, so showing a pic of a "gobbler" wont be possible, would just be a randon poult pic. Also there is no ID difference at that age on them for species, the other 4 subspecies, or a domestic bronze for that matter will all look the same.
They'll all be tan poults with brown and black speckles that are in the feathering out process.
At about 6 months, once the juvenile feathers start to molt off and the first adolecent feathers start to come in, you can then sex them. The hens will have buff laced tips on all their breast feathers for all 5 wild species while the jakes with be getting all black feathers no lacing at all. Hope that helped.
Sounds like you bought some, sorry just no way to ID them til they grow up and feather out good this fall.
There may still be some poult pics on my website, cant remember if they are still on there or not, but you are welcome to take a look and see
