4. Both can have beards, but toms will grow longer.
9. Both will display when young, but by the age of sexual maturity, only toms gobble.
This year I have done my own research on how to tell the sex of very young poults and chicks before they are old enough for the above! I have used a couple hundred poults to test as I hatched out Holland White, Midget White and A few Bourbon Red Poults this year, with 94% accuracy!
10. If you can hold the bird on your lap, laying on it's back, at any age, if it holds it's feet up close to it's back, it is probably a hen. If it extends it's legs or even just one leg, you probably have a tom. This, I find works with day old chicks and poults and seams to be based of their natural defensive posture of male vs female responses in these birds. I thought someone else might benefit from my findings, too, so I thought I would share.
I concur...the boys gobble and the girls lay eggs...two rooles I have not yet seen broken as far as genders in turks go...course maybe if the ovary quits on a hen...could she, mighten she...maybe gobble...maybe voice box is different...dunno?
Boys gobble
Girls lay eggs
BEARDS
LoREDa...GIRL
Black Bart - BOY (have spurs too but am thinking like chicken girls, probably have girl turks with spurs??)

STRUT YER STUFF (Hmm, stuffing...turkalurk stuffing)

Displaying or strutting...both genders do this BUT I find the more dominant hens strut more often... Happens a lot in the spring when jostling about regarding "pecking order" in the flock. The girl that struts is often lead turkey girl. This is Geri...
Jersey Buff hen Geri strutting her stuff.
Left - Black Bart (boy) and Right - Louise (girl). She was giving him a rough time that day...so I would expect under that wing a ding, she's clasping her ROLLING PIN...someone's gonna get a duke in the head...oh my!

This one I bet nobody has EVER seen before...heh heh heh...
I am thinking a SKIN TAG that grew feathers...Sweetgrass Tri-colour...this is Chiq...and her BOWTIE!!
Bwa ha ha...turkeys are always dressed (dressed for dinner...No NO...stop that...yummy yum...QUIT!) up so fine in their finery.
Interesting...about leg positions...will have to watch for that in future. Thanks.
