We do have a scratch and peck starter fee that is 20% protein. Our local feed store doesn't have the game bird starter, but I can look to see if they have something with higher protein.If you just want a protein supplement, try turkey or gamebird starter. It seems to range between 24% protein and 30% protein, depending on the brand. (How to serve it without wastage? Just add water, and they'll eat every crumb instead of throwing them around.)
TO serve we use this! We LOVE it! A bit pricey, but totally water and weather proof, and rodent proof. The ladies like it, and it hold a lot more feed then a normal feeder. I would suggest it to anyone really, it is fantastic!
