Let me redeem myself here:
I didn't say enough. By no means do I think chicken feed is a proper gut-load.
I use chicken feed for cricket breeding purposes.
It is cheap, absorbant, and is high in protein for baby cricket production. When the crickets are rady to become food, they are transferred to my other bins where they can be gutloaded.
My regular containers have no substrate at all, making it easy to scoop out the dead crickets, shed, waste and food spillage.
I use the premium mix from cricketfood.com and flukers gel to gut-load.
Man oh man oh man. Had no intention of spreading misinformation, nor did I try to answer a question that wasn't asked, nor did I try to ignore the question that was asked...just didn't make things clear.
It's just one of those days..
