Hmm, so far I do not think that is a balanced diet. The member I tagged knows a lot about making chicken feed by hand. Remember in most cases, it is very difficult to formulate a diet that meets the needs of todays chickens. If you have access to a commercial feed, it will likely be more conventional and cost affective to purchase it.
^^^ Is correct.
The ingredients listed are good for creating poultry with pasty butts and fatty liver disease, not much else.
@Cardi B welcome to BYC. STRONGLY recommend you not begin your chicken keeping journey by trying to craft feed for them. Its relatively easy to find feed (albeit more expensive) which is corn-free. Its much more difficult to find soy-free feeds (though they are made and can be ordered online, or stocked in larger feed stores).
Corn is a bulk "filler", but a useful one - it provides needed energy and is somewhat deficient in almost everything a bird needs to thrive, but its not so deficient as to make compensating for its weaknesses particularly difficult. Its also very cheap (compared to many other grains). For that reason it serves, and has served, as the basis for many chicken feed recipes for decades, if not centuries.
Soy is a legume, and the commonly harvested legume whose amino acid profile is closest to what a chicken actually needs. Not only is it high protein, but its relatively high in methionine, the first limiting amino acid critical to poultry development and maintenance. Methionine is responsible for connective tissue development and a well functioning digestive system. Birds raised on lower levels will never reach their full potential. Absent Soy, your feed will need another methionine source - a legume like alfalfa meal is sometimes seen as substitute, meat proteins (menhaden fish meal, crab meal, porcine blood meal), and/or a synthetic source (appears as "dl-Methionine" on the feed label). Methionine is so important to poultry development, and good plant sources are so few, that synthetic Methionine is allowed to be added to certified "Organic" feeds. But the total amount of synthetic methionine that can be added is limited by law - and is not enough to reach optimum targets in most cases without either soy or an animal protein source.
Unfortunately, feed which is both soy-free and corn-free likely has a bunch of other trendy words associated with it - Organic, non-GMO, whole grain, vegetarian, etc - all of which, in combination, tend to result in a feed which is expensive, nutritionally deficient, and potentially problematic in feeding (many users of whole grain feeds complain that their chickens, in accordance with pecking order, pick out their "favorites" and leave the rest for flock mates lower on the proverbial ladder, further aggravating nutritional deficiencies). To say I am "not a fan" probably undersells my feeling s on the matter - though there are steps you can take to compensate in part.
Target numbers for most chickens, for most of their lives, are 18-20% protein, 3.5% fat +/-, 3.5% fiber +/-, .3-.5% Methionine (younger chickens need more), .65-1.1% Lysine (younger chickens need more), around 1.5% calcium (more for hens while laying, amounts vary by egg size and frequency), about .5-.6% non-phytate phosphorus.
Oats are low protein, high fiber, high fat. They contain large amounts of beta glucans, which slow digestion and contribute to pasty butt. Decent sources of Lysine and Threonine, low in Methione, a bit lacking in Tryptophan.
Flax is good protein, high fiber, and massive fat. Its amino acid profile is one of the best in the seed family. Unfortunately, its fat content is TEN TIMES the recommended level for poultry. Its about as healthy in quantity as you taking a multivitamin in a stick of butter each day.
Compared to flax, BOSS is lower protein, higher fiber, and even more massive fat. Its amino acid ratio is tolerable, but not superior in any fashion. Think of it as a generic multivitamin, served in deep fried butter.
Safflower seeds are more expensive than BOSS as they usually come dehulled, which lowers their fiber to more reasonable ranges. Their amino acid profile is across the board inferior to BOSS, though they have similar total protein levels, and their fat levels are (like flax) only about ten times the levels recommended for a healthy chicken.
BSFL. Dried or live? Live, they have good protein levels with an excellent AA balance, good fiber levels, and they are only 4-5x more fatty than recommended for a chicken. Dried, they have exceptional protein, but about 10x the desired fat content. Similar numbers with mealworms - useful, perhaps, in small quantity, but so nutritionally dense they easily imbalance a complete diet due to their fat content.
Without knowing your table scraps, I can't speak to their nutritonal values.
That's my off the cuff thoughts. Hope you find it helpful.
