Well, my decision was nearly made for me at TSC yesterday. Agway had small bags of MannaPro and something I'd not heard of. TSC had Dumor (of course) and Purina Starter/Grower. The Purina was the only medicated starter feed, and of course couldn't be purchased in anything other than the 50-lb bag! I got the only one left.
My chicks hatch June 11. They'd better be hungry! I don't know how long you can have the food while maintaining its quality and I know it's best to buy what you'll use within a few weeks....but had I waited until just before chick arrival I have a feeling there would have been none.
There were no Sav-a-Chick packets either. Boo.
