think if you put a pot of beans or peas in the box when yb hatch it does not matter what your feeding use to be you wanted at least 18 to 20 percent protein for breeding in a mix but if you give them the protein high feed beans or peas in the box it should not matter what your mix is my best tip for rearing healthy yb is plenty kilpatricks black minrals tried others but thay crave for the kilpatrick stuff if its the salt there after as some say they have the balance just right imo
