Kilgus farms in fairbury. That's where I am going to get cow manure.it's not free. Everywhere else has horse manure usually free. Or manure that has alot of different animal mixed with horse manure. I guess if you know a dairy farm you are in luck. Horse manure is good but it has a ton of weed seeds in it. I am trying to fill some new raised beds and I want them to be mostly compost and leaves. I don't want weeds.lol
