Help? Whole Grains??

ingredients are measured by weight, not volume, and your mix doesn't include the vitamin/mineral mix they need, or the correct amino acids in the right amounts. Also, your birds will pick out the yummy stuff, and leave the rest, so probably the dominant individuals will eat the tastiest items, leaving the least favorite seeds for the less favored individuals.
None of that will be good!
If you have small game type birds, and live in a varied environment all year, your birds may manage. If you have more modern type hens, who are designed to lay 150 to 300+ eggs each year, they will be malnourished.
