If they are still this young then they might have no natural interest in greens yet, as they grow older their interest should change.
They need allot of protein when young as they are growing very rapidly. Feeders are their first inclination.
Keep a proper dusting schedule
up to 1.5 years - calcium 5x per week / vitamins 2x per week (one(1) dusted feeding per day)
1.5 years + - calcium 3x per week / vitamins 1-2x per week (one(1) dusted feeding a day 4-5 days, 2-3 days nothing dusted)
Gravid female - calcium 5x per week / vitamins 2x per week (one(1) dusted feeding per day)
sick dragon - Unable to dose, due to variables of illnesses
up to 1.5 years butterworm/BSF larvae diet - calcium 2-3x per week / vitamins 2x per week
1.5 years + butterworm/BSF larvae diet - calcium 1-2x per week / vitamins 1-2x per week
Stay away from chitinous feeders such as mealworms and superworms. Only feeder crickets that are appropriately sized. The cricket should be no longer in length then the distance between the dragons eyes. Other soft bodied feeders fall outside of these rules they can be fed larger then the space between the eyes but, you should still use your best judgement, they will try to eat any sized feeder, this is potentially harmful if not possibly fatal to young dragons.
keep a good routine of
bathing. 2-3 times a week in 93-96°F shoulder height water for 10-15 minutes each
bath period.
Consider separating the dragons soon it is only a matter of time in most cases till something adverse happens. It is my advice to separate before the potential risk elevates into a physical threat.
