Hey there
Looks like a healthy emp
However, you'll have to put it on some cocofiber or peat moss instead of those wood chips.
Emps are forest scorpions and need moist, humid environments and one of the best substrates to hold humidity is cocofiber.
As for your question, I'm not sure.
We'd first have to see if it's even a female. But from the looks of it, it appears to be an adult scorpion.
To sex it, you'd need a pic of its underside, where the pectines are. From that area we may be able to determine male/female. Some people have taken the pic by placing the scorpion in a clear container or a clear plastic bag for the shot.
