Females are supposed to weigh more right?

[SweetieChicken234]

My jumbo male is 14.6oz right now(few males about his weight) and my females are 12 and 13oz. All the same age. They are 6 weeks old tomorrow.

I thought females were heavier. Is this different with jumbos?

Generally females are bigger than males. Like any species, though, there are exceptions.
