Way too many factors to be able to isolate a cause. You really have a responsibility to feed them properly and 15% protein is akin to feeding a human child only top ramen noodles it's whole life, or feeding a dog only cat food. They are from the other side of the world and have a biology that has developed over many thousands of years. They need no less than 20%, at least if you can't do anything else please switch to flock raiser, it's not great but it's miles better than layer. They really should be getting 24% protein but at least won't suffer from 20%. Your thrift level should increase dramatically as well.
Not using full spectrum lighting can also cause vitamin D deficiency. LED lights do not qualify as full spectrum. Things don't "get" vitamin D from the sun, they need full spectrum lighting to properly metabolize the vitamin D they get from other sources. You're forcing them to do something that is directly opposed to what their metabolism is programmed for, and then doing it in a way that can have even further negative health impacts. They will already live a much shorter life because of forced production, and you can count on it being further shorter with improper lights and poor feed.
Flushing deaths can usually be avoided by having ceilings either too high, too low, or have a soft barrier attached a few inches below the roof.
I'm not trying to pick on you but these are exotic animals essentially and we have a responsibility to go out of our way to care for them since we went out of our way to get them.
