Hello,
It is a possibility she could have hurt her wrist on the hammock, they have been known to contribute to injuries.
The
UVB light you have though, while high output, is a compact/coil UVB. They tend not to distribute UVB evenly. They spike, then fall way down on output. A lot of times, their UVB wavelength is incorrect also, not providing adequate wavelength which is conducive to D3 synthesis.
We normally recommend tube bulbs or mercury vapor bulbs. There are some T5 high output tube bulbs which have terrific performance on UVB. The Reptisun 10 or the Arcadia D3 12% either one would be a great choice.
How often does she get calcium supplementation?
Are you using a digital probe or temp gun to measure the temperatures with?
Let us know how she is doing.
