Oh NO Mold in the food!!! How much harm did I do???

[Missouri chick]

This morning I stared to fill up feeders in my layer pen. I usually throw one scoop out on the ground to occupy them while I'm working. I'm at the bottom of a bag of food and saw mold. How much damage did I do???? What do I look out for???? Yes, I'm going to get more food today and clean out the bin before I put in new, but I'm worried. PLEASE HELP!!

I'm sure they'll be fine. Watch for any signs of illness in the next few days. My chickens have cast iron gizzards.
