You will never get accurate information from feed store employees. That's one of the immutable laws of life.
Many of us old timers here on BYC gave up juggling layer and starter and grower for a mixed flock years ago and now just feed grower to everyone in the flock. The only "issues" it would raise is with your laying hens not having access to enough calcium. That's what oyster shell is for.
You make it available free choice for the layers, and they eat of it however much they need to satisfy their needs. I attach little tins on the walls at intervals around the run so they always have some handy when the calcium "urge" hits.
And while we're on the subject, grower is fine for new chicks, also. I was in the feed store last summer picking up a bag of starter for some new chicks I expected to hatch, and I decided to compare the labels of Flock Raiser and the chick starter. The ingredients were practically indentical, the only difference being the grower was a tad higher in protein. I've raised multiple sets of chicks on grower now with no problem.
It sure simplifies things, let me tell you.
