Any Public Datasets That Focus On Nutrition Content Of Eggs Based On Chicken Feed? Maybe More Specifically, Transfer Rate Of Certain Nutrients From Chicken Feed Into The Egg?

Was looking for datasets with nutrition content in mind and perhaps feed efficiency rate but now I realized I’m struggling to find any dataset related to egg size, shell hardness, and contents. I’m checking FSIS and USDA but most studies are focused around incidences of contamination and the like rather than product quality, perhaps due to only having “standards,” but that means they should have the data somewhere and I just can’t find it, right…? Please help 🙏
