Medicated or non-medicated feed?

[GC-Raptor]

In my anxiousness for our chickies to arrive, I bought a 50 pound bag of medicated feed. We will have 10 chicks.. Should I swap it out for a smaller bag??

With 10 chicks it'll be gone within 2 months.
How soon will you get the Chicks?
What's the mill date on the bag?
It'll be on the bottom sew seam of the bag (Purina) or the tag (Nutrena). GC
