I wanted to add that LDL is the bad form of cholesterol, not HDL. Like the other respondents, I don't know that eating quail eggs will reduce LDL, but anecdotally, I've been raising quail for 2 years and have eaten very few chicken eggs, but lots of quail eggs in that time.Until recently, I'd been unmedicated since 2021 (had differences of opinion with my primary care physician and my cardiologist and fired both). My HDL and LDL are good. My triglycerides are a bit elevated, but that's been the bane of my entire life even since my 20s.
I raise jumbo wild coturnix and can generally sex them at 3 weeks, but I did have one male fool me in my first hatch.
I'm in the Dallas area (ignore my user name, I haven't moved to Clifton, yet). If you're near, I'd be willing to set some eggs and sell you the resulting day old chicks at $3 each. I think that's the going rate on Craig's List. There are a lot of quail keepers in Texas so you should be able to find someone nearby.
