I would go get a fresh bag of chick starter, I know you want organic, but you may have to use something like Purina Start & Grow or even Flock Raiser. The bag of feed you have is 10months old, that's too old in my opinion. I won't buy if it's more than 4 weeks from mill date. Find your receipt, take back that bag and ask for a refund or exchange.I started them on Corid today.
The mill date on the bag is 01 2018. Is that good?
