Scratch is a treat, not a complete feed. Scratch only has 6 to 8% protein and all poultry need a minimum of 16% or more. Ask at the feed store where you get the scratch about a complete feed such as game bird or meat bird food. At their age chicken layer feed wouldn't be the best for them but it's better than just scratch. And guineas need grass to keep their digestive system working properly.
Personally I think it is wrong to keep guineas caged. They should at least have 10 square feet of covered run per bird. Once they have accepted your home as their home, usually at least a month of confinement, you might try letting a few of them out to free range. Always making sure they are confined at night!
