For a 4 year old, once week is definitely enough. As for the wrapping, she seems to have a good feeding response. Maybe this is the time to start hook training. Touching your female with the hook first and move her head out of the way where you can comfortably grab the middle of her body without risk of her biting you.

Do you feed in the enclosure or out of the enclosure for both your male and female?Do you feed live or F/T? How big in grams is your male?
