My male is about 80 grams, and he is a normal high yellow. My female is also a normal high yellow, and she weighs about 67-70 grams. A lot of it i think is genetic, and a lot their eating habits. My female eats like she should, and is always in good health. My male I have to be sure to not over feed, as he would eat anything in excess (heck, when i go into his cage i am often startled by him biting onto my finger tip thinking it is a worm!! lol). If i fed him pinkies he would probably be over 100!
...and ignore the math genious who felt it necessary to correct your ounces to grams - anyone with intelligence understood you meant grams. Some people just cannot resist i guess (same way i could not resist making a comment...)
