Turkeys and cracked corn

[ChickenCanoe]

Ideally, turkeys should be getting 28% protein the first 8 weeks, 20-22% till 14 weeks and 18% after 14 weeks.
Mixing a 24% starter with 9% corn for 8-10 week poults, you would need to mix 4 parts corn to 11 parts starter to get 20% crude protein.

Keep in mind that you aren't just diluting crude protein by blending in lots of corn but also all the vitamins and minerals the birds need.

If you mix an 18% starter with corn 50:50, you'll end up with about 14% protein. I'd say that is way too low.

I’m feeding 22% protein bought them in November and they are going though it like candy can I mix the cracked corn as well?

That depends on how old they aree? Galliform amino acid requirements vary dramatically with age. Which is true of many animals but especially game birds. If they hatched, presumably November 15, that makes them about 8 weeks old. If they hatched November 1, they're 10 weeks. End of November 6 weeks.
From that number, do the math.
If they're 6 weeks, 22% is still insufficient. If you were feeding 22% when younger poults, they needed more. Most game bird starters from companies like Nutrena and Purina, run between 29 and 32% protein. I wouldn't cut the 22% with corn yet. They may need more protein a bit longer since it has been low. I don't know how much that will help but their bodies are still growing quickly. After 12 weeks, you can start mixing in some corn.
If you do the math using the Pearson's square in the link I posted, mixing 3 parts corn to 12 parts 22% will yield 19%. That is good to 4 months. For the next month, you can go with a 2:1 ratio.
In nature diet can be all over the board. But generally speaking, parents will lead the poults to eat mostly invertebrates like insects, worms, snails and even rodents, lizards and snakes (high protein. especially essential amino acids). Gradually adding more seeds, forbs. tubers, shoots and fruits as they grow. There are surely people who are not as strict on crude protein numbers but the research shows the protein for optimal growth according to poultry nutritionists. I think it is important to follow the research because the natural foods poults eat are likely higher in lysine, methionine and other essential amino acids that grain/legume based commercial feed, like your 22% have and those companies need to supplement with synthetic essential amino acids.
I hope this helps.
