Newly bought Dubia. Female adults being dominant over males?

[Telepizza]

Hi there!
I got a little amount of dubias (10) yesterday, of which 8 are females. One of them is a nymph still.

There are two really big females.
After reading and calculating the breeding process, because I only want to breed them for my single leopard, I thought I'd put one of the big females with one of the males apart of the colony, hoping that they mate.
This way, only having one pregnant female, I could calculate how many I need to breed in order be productive for my girl's feeding, and not ending with a whole bunch of roaches left.

What happened was: the female kept following the male, this one running away, and she would just lay on top of him at a corner. I chose her because she's the biggest, along with the other one, and in case they were already pregnant, that wouldn't add yet another female to the count.
I tried getting her with the other male and did exactly the same.
To be honest both males are pretty "coward" in general.
At this moment each male is in a different smaller tupper, each, and both inside the main tupper.

Does this behaviour mean she's already pregnant, and she's being territorial about the males?

I have no idea!

How are they setup? Photo? I don't know whether the setup makes a difference.

• Does your dubia pair have a place to hide like a section of egg carton? Maybe they like privacy? :coverlaugh:
• Try a female that's the same size as the male. Maybe these males are "first-timers".
