You should be feeding him/her 3 times a day for 10-15 mins at a time, as many as they will eat in that time. 20 crickets is no where near enough. Havoc was eating 100 or so a day when he was a baby.
normally with a baby bearded dragon you want to try feeding it 2-3x a day as much as it will eat in 15 mins. but not all bearded dragons will eat like that. my bearded dragon who is nearly 5 months old just gets a dish of calci worms and small dubia roaches put in her viv in the morning and she eats when she wants to.
i dont count how much she eats, but depending on how hungry she is she can easily eat 100 large calci worms and 50 small dubia roaches
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
