I'm glad you reported it. It's bad for their business to have moldy bags out there. There are so many spots on the supply chain that it could've happened. I have not heard anything bad about Modesto - I'm sure they will investigate it.
Did you have the mill date/lot number to give them?
You could still provide organic feed. Try a fence to contain your birds.
I understand all that. The post confused me by not considering organic feed because of what is grown nearby.
