What do you use to clean your goat pens? I have 2 manure forks, one is a "regular" one with tines that are about 1" apart, and the other has tines that are 1/2" apart. The regular one is lighter and easier to use but the goat poop falls through unless it is mixed with hay. The one with the 1/2" tines works better but a lot of the poop still falls through and I never feel like I am getting their pen as clean as I would like it to be . Any suggestions?
