Here's another approach to assessing the quality and adequacy of the diet for you and your chickens (instead of trying to count or calculate fractions of a gram of something, or looking just at gross protein, carb and lipid analysis of a sample specimen of each item in splendid isolation):
"The MDD-W indicator was developed by FAO and partners to fill the need for a simple, food-based indicator for measuring dietary diversity and micronutrient adequacy, key dimensions of diet quality of women of reproductive age. This population–level qualitative indicator measures the proportion of women 15-49 years of age who consumed food items (at least 15g) from at least five out of the ten defined food groups the previous day or night. It is associated with a higher probability of nutrient adequacy for 11 micronutrients. "

NB the guide is 176 pages long; the key point is
"MDD-W is a dichotomous indicator of whether or not women 15 to 49 years of age have consumed at least five out of ten defined food groups the previous day or night. It is a food group diversity indicator that reflects one key dimension of diet quality – micronutrient adequacy – summarized across 11 micronutrients: vitamin A, thiamine, riboflavin, niacin, vitamin B-6, folate, vitamin B-12, vitamin C, calcium, iron and zinc. The proportion of women of reproductive age (WRA) who achieve this minimum of five food groups out of ten in a population can be used as a proxy indicator for higher micronutrient adequacy. In other words, a higher prevalence of MDD-W among a group of WRA is a proxy for better micronutrient adequacy in a given population (Martin-Prével et al., 2015)."
And the ten food groups are
1. Grains, white roots and tubers, and plantains
2. Pulses (beans, peas and lentils)
3. Nuts and seeds
4. Milk and milk products
5. Meat, poultry and fish
6. Eggs
7. Dark green leafy vegetables
8. Other vitamin A-rich fruits and vegetables
9. Other vegetables
10. Other fruits
If you and your chickens are eating at least 15g of at least 5 of these food groups in 24 hours, you and they are probably getting all the micronutrients you need.
