A lot of people myself included keep them on high protein. They require more than chickens.

Cots mature in 6-8 weeks so it's not necessary to use 3 different types of feeds like you do with a slower maturing chicken or turkey. You can use starter till laying age then switch to game bird layer. For simplicity's sake most people feed starter forever and supplement cal on the side, but starter is designed for growing birds and isn't ideal for mature birds.
