By scratch I'm assuming it's a mixed whole grain, oats, corn and I think barley.

It's been a few years since I fed it. The chickens don't like the oats so I felt it was a waste and stopped feeding it.

I was feeding it to chickens and geese at the time. Now I feed cracked corn and during the breeding season turkey pellets. But then I'm also feeding peacocks. Chicken food isn't good for the peacocks but I know the ducks don't like the powdered feed they prefer pellets.
I was feeding 4 scoops of feed during the winter and they were still hungry.

Now I feed one scoop and there is feed left over.

That makes the rats happy.
Bandit my muscovy duck loves to help the cats eat not only their cat food but she drinks the goats milk with them.
