Thanks my local feed store just started carrying BackyardFeed this week - 50# for $35 so will stick with them. Thanks & good luck to you. I usually ferment, but can't in the Summer since it draws flies - though maybe it was an ingredient in the Purina- hmmmm??
Sorry I missed your calcium question. If the feed is stating oyster strong then no you don't need to provide. I fed all flock (higher protein) so did offer oyster shell but not sure they really ate it. I only saw them tump the saucer over.
Sorry I don't have a Purina label. I had been feeding Purina All-Flock & it was not organic. I've just switched over, so not long enough to notice difference. I just like the fact that it's local, small business & the freshest available. When I'd buy Purina at the feed store it was ~3 weeks old...
Here is the link they have various life stages along with soy & non-soy formulas. I'm excited to be able to offer my girls something other than Purina and to know it will be the freshest I can buy!!

I just discovered Backyard Feed Company. It's in FL & they offer free shipping. Know it's not ATL, but it's your neighboring state, organic & soy free. I read they mill upon order & ship.
