Feed Recipe Builder: the complete guide
Mixing your own feed is the one place backyard keepers can genuinely undercut the feed store, but only if the mix hits the protein and calcium the birds need. This builder takes the ration you are feeding, the ingredients you can source locally, and the batch size you want, then returns the recipe by percentage and by pounds with the finished nutrition worked out.
How the feed recipe builder works
- Every ingredient carries a published crude protein, calcium, fat and fiber figure. The builder weights each one by its share of the mix to get the finished ration.
- Grains form the energy base, then protein feeds like soybean meal, field peas and fish meal are raised in one percent steps until the mix reaches the target protein.
- Each ingredient has a practical ceiling. Oats above about 25 percent is too fibrous, fish meal above 10 percent taints the eggs, and flax above 5 percent softens the fat.
- Calcium is handled separately. Layers get oyster shell in the mix, and every other ration leaves it out because high calcium damages the kidneys of birds that are not laying.
- Cost per pound comes from typical retail ingredient prices, and the comparison line uses your own bag price so the saving is real rather than theoretical.
How to use it
- Pick the ration that matches your birds: chick starter, grower, layer, broiler or all flock.
- Tick every ingredient you can actually buy nearby. The builder will only use what you tick.
- Set the batch size in pounds, usually one bucket or one barrel worth.
- Enter the price and weight of the bagged feed you are replacing.
- Read the pounds column straight onto the scale, and check the protein line before you mix.
Step by step examples
Layer ration from corn, wheat, peas and oyster shell
A 50 lb batch lands near 40 percent corn, 25 percent wheat, 25 percent field peas and 7 percent oyster shell, giving roughly 15 to 16 percent protein and close to 3 percent calcium. Offer extra oyster shell free choice and the hens self correct.
Chick starter without soy
Corn, wheat, field peas and fish meal at 8 percent gets a starter to 20 percent protein with no soybean meal. Leave the oyster shell out entirely for chicks.
Recommended values
| Item | Value | Notes |
|---|---|---|
| Chick starter protein | 20 to 22% | 0 to 8 weeks |
| Grower protein | 16 to 18% | 8 to 18 weeks |
| Layer protein | 16 to 17% | |
| Layer calcium | 3.5 to 4.5% | Plus free choice oyster shell |
| Broiler protein | 20 to 22% | |
| Fish meal ceiling | 10% | Above this eggs taste fishy |
Common mistakes
- Feeding a layer mix with full calcium to chicks, cockerels or birds out of lay.
- Building a mix from corn and scratch only. Scratch grain is about 8 percent protein and will not carry a laying hen.
- Skipping grit. Whole grain rations need insoluble grit because the gizzard does the grinding.
- Mixing more than a month at a time. Ground feed goes rancid and loses vitamins quickly.
- Assuming homemade is always cheaper. Check the cost per pound line before you commit to a barrel.
Frequently asked questions
Is homemade chicken feed cheaper?
Usually yes on grain heavy layer rations bought in bulk, and often no on high protein starter, because soybean and fish meal are expensive in small bags. The cost line in the builder tells you which side you land on.
What protein do laying hens need?
About 16 to 17 percent, with 3.5 to 4.5 percent calcium. Below 15 percent, egg size drops before egg count does.
Do I need to grind the grain?
No, whole grain works well as long as grit is available. Grinding suits chicks and very young birds.
Can I feed the same mix to chicks and hens?
Use an all flock ration at about 18 percent protein and put calcium in a separate dish. That is the only safe way to feed mixed ages from one bag.
