Feed requirements for started pullets?

[Minflick]

My new teenagers arrive in a little over 2 weeks. What kind of feed do I need to have on hand for them? I know I need grit and oyster shell, but I don't know what kind of regular feed I need. They're coming from Murray McMurray, and are supposed to be around 15-22 weeks old.

I would feed Flock Raiser or something similar with oyster shell and grit on the side, until they are all laying, then either continue the same or switch to Layena. The pelleted feed has less waste, which helps. Mary
