Male bobwhite does female call

[larbian]

I have 4 female and 3 male Bobwhites.

The males make the call like a female not the normal "bobwhite".
I hatched the birds myself.
Do i have a different breed of Bobwhite that doesnt call "Bobwhite"?
Will they eventually do the normal call?

They are about 6 mths old and on wire.

Thanks to anyone that can explain.
