Thanks a lot

Experienced professionals can determine sex practically right out of the egg. I need them to be 4 months, give or take.

I would think that by 5-6 months it would be very apparent which gender a leo is. I've also had some "late bloomers" who didn't show signs of their "manliness" until later and then suddenly went through rapid growth spurts. The late-bloomers can be a bit tricky! Try getting one of those scientific super-powerful hand-held magnifiers. It will help SO much.

Females have the pores too, they just aren't so prominent/dark and don't secrete a waxy substance like the males. The hemipenal bulges are a sure sign that a leo is a male. Males also have broader heads while females are more triangular in shape. And the males start to become noticebly larger than the girls at 5-7 months.

I have three sub-adults that hatched about the same time, one female, two males-- the female was the biggest and fattest for the longest time, but now the males are much larger than her (she is still a fatty). Both boys are bigger and exhibit the above characteristics but one of the boys is now easily 1.5 times her size and has a muscular density that she lacks...and his poop is elephant-like in comparison! He's a total "poop machine" while she's "a lady".
