It's probably relocation stress then, it tend to hit them after a couple days in their new home. Perfectly normal. :wink:
OK, for no you can replace the red light with a normal white light bulb. White light is actually better for them than red light, and it encourages them he be more active and helps with their appetite. Just keep taking her outside until you get a UVB light. I'm not sure what brands are available in SA, but ReptiSun 10.0 and Arcadia12% are the best.
And syringe feeding her is perfectly safe. Most of them LOVE squash baby food, so she will probably lick it right up.
For veggies, some will just like them on their own, but with my beardie I have to limit his bugs so he is actually hungry enough for his salad. Don't worry about that until she is at a good weight though, she needs more bugs right now until she is chubbier. How old is she?
And my beardie is usually active in the morning, and spend the afternoons taking a nap. So it just depends on the individual I guess, but you don't want her sleeping 24/7 either. Once you get a white light and a UVB light, she will probably be more active. Do you have a thermometer in your viv?
