Hogs? Certain breeds of chickens - you bet!
Let me tell you something about poultry... chickens will eat a lot more grain than ducks and ducks will eat more than geese when they have access to pasture. Some chickens can be pigs.
But recently, I noticed a serious uptick in grain consumption. Mind you, I'm raising a few turkeys for our Thanksgiving meal, several guinea fowl, and I have about twice as many juvenile chickens out there right now as "on staff" layer hens so I, naturally, thought that those babies (and those dang turkeys) were seriously gobbling up the chicken chow. I would fill all the bowls each morning and when I returned in the late afternoon the bowls were licked clean. The most surprising thing was that when I came into the henyard with the feed bucket I was mobbed by starving birds.
I thought... wow! that's over 25lbs of feed just in the morning, but I put out an extra tray of kibble for them.
