How can I tell if my 3 baby Sulcatas are being over fed? Am I supposed to measure out their food daily? How much? What I'll usually do is feed them, and whatever is left when it starts to look "wilty" I throw away. A few hours later I'll give them some more. I usually do this 3,4, or sometimes 5x/day. Am I over feeding??--Thanks in advance for your help!
