Are you feeding the Broad Breasted Turkey starter, which is 22%, or the Game Bird Starter, which is 30%?
It's probably true that the companies make a higher profit on the lower protein foods. But that's not the only issue. Some breeds of chickens have significant joint problems when fed too high a protein diet. They should grow slowly, but the high protein food makes them grow too fast, and their joints don't have time to develop adequately. In some breeds, the lameness rate is as much as 40% by 5 months of age. So the lower protein food for chickens is better for long term health. The difference between 18% and 24% isn't a big deal for most breeds (although some long term breeders of certain breeds say they notice a problem starting at 20% protein, so they start with 18% until 12 weeks old, then drop it down to 14-15% for the breeder cockerels -- the ones they want to be able to walk well for 7-10 years). But the difference between 18% and 30% is huge for most chicken breeds, and I would never feed such a high protein level to any dual purpose chicken that I wanted to keep as a breeder. Even if they make it to adulthood without lameness, there's an increased risk of arthritis as they age.
