I really need help guys. I've had my baby boxie since the beginning of October. He's been eating a variety of food like earthworms, reptomin, red leaf lettuce, berries, calcium etc. He has a heat lamp and also UVB. About 2 days ago I noticed a part of his plastron looked somewhat flaky and lighter than what it's supposed to be. Today I picked him up and checked his plastron again, the light discolored area is still there and she also seems soft on her plastron. She's approximately 2-3 months old, is this normal? I attached a picture.
