A trurkey that sings to me

I have a Turkey that sings all day long , I had 6 and gave away 2 to a friend . But out of them all my one turkey sings . It started the day I got them , and only one does it is this the norm? I got them when they were one day old and they all are white meat turkey.
But only one sings , as I'm doing things I whistle back to it and it does it back each and every time. I'm sure that this has nothing to do with weather its a boy or girl it just likes to sing. Not to sure why but I had 6 and now down to one as everyone wants a turkey as I got them late in the season from a place around me . I'm not even sure if I have a turkey 100% as I was told that my black ones were going to stay 100% black well they are getting white on them and was told 90% females but if you don't know what to look for as I'm a first timer this year and I'm ready to take in some for meat and keep my favs for egg layin & babies next spring as I got to sick for doing the incubator thing I got ulcers bleeding ones over watching the temp & all. But is it the norm for a turkey to sing all day long ? I feel dumb as I have read tons all last year about birds and my chicks talk but not even them sing. So should I take my turkey to sining classes lol just kidding but would like to know if this is the norm for them??? Hope everyone have a great Friday

What sound is it making that it sounds like singing? Turkeys do have a trill call they will do, usually a hen does it. You said you are unsure if it's a turkey? If you have white turkey meat breeds than they won't be able to reproduce and they won't live very long, you would need to get some heritage breeds.

My two turkeys are just starting to get the naked head, but they'll follow me around the garden trilling and purring after I let them out of the run. It seems like a happy, contented noise to me.
