Feeding almost layers and older babies

[acbowers]

I have 9 "almost" layers (expecting some eggs within the next week or two) and 7 "babies" (layers too) that are 4 weeks behind the older layers. I need to buy more feed (which lasts about 3 weeks with this flock). Currently I buy Purina Flock Raiser (20% protein) but I wanted to switch to a 15-16% protein Layer Ration when they started laying. Should I just go ahead and buy the Flock Raiser until they are all laying and just offer oyster shells? Will I have issues with the "babies" eating the shells? Any other recommendations? Maybe I'm making a big deal over a 4 week age difference but this is my first flock.

There are all kinds of feeds that EVERYONE can eat. Flock Raiser is one of them.

Only the birds actually in lay need the high calcium additive. In my experience, only the hens who are laying usually show much interest in the calcium source offered free will. This method of management works for thousands of people successfully.
