I've got a question about Start and Grow, and hoping you all can help me with it. I have just used up a 25lb. bag of it, and it smells very "grain-y". It is kept in a galvanized can, inside my house, where it is cool. Whenever I open the can to get some out, its quite warm inside?? I just opened a new bag, because I'm almost done with the old one, and it feels "warm" just like the other bag, and smells the same?? Plus its darker too. It makes me kinda worried. The hubby says it must have gotten wet, but I don't see how. Like I said, its kept in the house, and my Layer feed is kept the same way too, and doesn't smell like this at all! I don't want to hurt my little ones. They have been fine thus far.
