All the birds can eat Starter (non medicated) or Grower. My feed company only sells Starter/Grower, a combined product at 18% protein, and another company I use only sells Starter/Grower that is 18% protein. Essentially, a 20% Grower is what Purina calls Flock Raiser, a feed that can be fed to everyone.
If you are concerned about your heavy layers getting the calcium they need, you can offer eggs shells, calcium carbonate ($4 a 50# bag at most Ag stores) or the popular oyster shells on the side. Younger birds don't normally mess with calcium offered on the side as their bodies are not craving it.
