I *know* I've seen it before. I can't remember where. I only have 12 Cornish, but I'm thinking about bulk ordering some feed from the bill. We store the layer feed/BOSS/scratch treats in food grade blue barrels, and I can get more of them. I think I'd like to get a dozen or two Cornish cross at a time, probably every month, just to stagger my processing (since I'll do it here). But the question is, I'm trying to decide what to order feed wise, and how long it would last. I don't want to deal with rot, but the more I order, the cheaper it gets. But where is the chart? LOL!!
