I think i would stick to the formula specific to the chicks you have and there ages.
I use the wild bird starter for my guinea babies and i believe it is also for turkey amongst other.
If you do over the recomended levels of protein it could result in bone, muscular or other leg problems. I am no nutritional expert,but i have had leg problems in my chicks in the past when i did not feed the appropriate formulas at the right stage.
