With bagseed it is not uncommon to get feminized seeds. It is less common to get hermaphrodites, but that can happen too.
Growers often over feed plants. That stresses a female plant into producing pollen. The resulting seeds are feminized and will produce female plants. If you stress them the same way as the grower did, they will produce male flowers.
Actual hermaphrodites are a bit more rare.
I would not be surprised if all 10 were female.
BTW, over feeding is by far the most common mistake that leads to a female plant producing unwanted male flowers.
It is usually the grower's fault, not the plant's.
