I think I might have to start feeding my chickens garlic. Apparently, It makes their poop less smelly (although with the sawdust, this hasn't been a huge problem) and could possibly reduce the cholesterol in their eggs.
I have read that putting a crushed clove of garlic in the water helps keep chickens healthy too.
On a different chicken-feeding note, we have discovered that the chickens LOVE grape leaves. They ate the leaf I'm holding in this picture in a frenzy.
