A few days ago I bought a 25 lb. bag of chick starter from a local feed/hardware store. I opened it tonight, and it smelled... stale. Didn't look bad, didn't seem damp or moldy, just smelled old. I even compared it with a tiny bit of other starter I had left - the other smelled fine. My question is - will it harm my week old Seramas? I will try to return it to the feed store, but I don't know where my receipt is and I don't have any other starter on hand, so they'll have to eat it tonight or I'll need to go wrangle up some alternative food to tide them over until tomorrow. Edit: In case it's relevant, the brand is Kelley's. I may just need to bit the bullet and drive an hour and a half to the nearest TSC tomorrow and get Purina.
