I'm not trying to be harsh here, and I haven't read the other comments, but this girl has MBD. I dont want to hurt any feelings, but if you were only using a deep dome with a single UVB on top of the screen this was probably the largest contributing factor outside of using the calcium on the feeders. A deep dome specifically for chams is dangerous on top of a screen cage. There a large distance between the bulb and the screen and the screen is already filtering a huge amount of uvb. Linear is used in general because it's a consistent uvb at an appropriate levels. Domes can be used but you need to be using meters to measure the uvb. I'm sorry that this has happened but MBD is almost completely preventable.
