When you find the one or two greens that she really likes, use those and add in one or two other items in her salad. mix it together well so she can't just pick her fav's and she'll get pieces of everything. I use a cheese grater to shred the pumpkin or butternut into thin strips, all the dragons really enjoy it. It can take a few weeks to really get them eating their veggies. Even a bite or two is better than none at all. When they are babies to 1 year old, they need more protein (especially from 2 to 10 months) because this is when their growth rate is th most rapid. The favorite greens for all of mine are dandelion greens, mustard greens and endive. I try to rotate these so that one week I combine two of these, the next a different combo, sometimes a mix of all(if I happen to find all avail at the same time that look really fresh). Put the greens in the viv first
thing in the morning and wait to feed protein for about 45 min to 1 hour later. Sometimes this also helps, they warm up and are hungry and this can encourage them to get into the salad before filling up on protein.
Don't worry, she'll get there, some dragons are more picky than others.
