Turkistan Roaches Reproduce Without Any Males?

[Paradon]

I looked over my Turkistan roaches' bin and I see some females and small nymphs, which I have never gotten after the first batch! The weird thing is: I haven't seen any adult males, which have wings. All I see are smaller immature or females, but they seem to be producing oothecae without the males and I see tiny little roaches running around everywhere. This is the first for me. Either that, or in my colony my males have no wings. It can't be from the first batch I got because that was a long time ago and all the nymphs have grown quite considerably and I see oothecae everywhere, but no males.
