mine dont really care for apples. they love bannana(they eat them whole), papaya, mango, avacado, grapes, melons, berries, oranges,(no seeds)... you have to try different ones at different times and see what yours likes (taste will change over time). stick with bite size. When we feed turkey burgers they also get greens mixed in with fruit. I don't think you will have a problem with overeating of fruit. The older they get the more they will aquire a taste for it. with younger ones we hide a lot of it in the turkey.
Check out www.beautifuldragons.com for a list of fruits. Look for stuff hi in vitimal C too.
Fruits are essential for healthy skin and clean sheds.
Brumation is like hibernation but not a deep sleep. when winter rolls in, daylight hours are less and barametric pressure changes they will sleep more and eat less.
