How Much Protein for Dual Purpose?

[Menmyrc]

I am raising BOs as dual purpose. Right now they are 7 weeks old and are on 21% protein starter mash with amprolium. Once they have been outside for a time I will quit giving them the starter mash. Considering I want the roos to be freezer ready between 18-24 weeks, how much protein should I provide? The "grower" feed is 18% protein. Should I find one higher or is 18% sufficient?

Thanks

I would think 18% is fine, especially if they will be out free-ranging some.
