I had put these together a few months ago, and finally put them up today for the goaties! They LOVED them. I love them too--they are super easy to make and install, and super easy to refill. I installed one on each goat house, underneath the roof overhang. When I get my new memory card I will take some pictures for you. Until then, if you are a goat keeper, please enjoy this video tutorial by applegoat9!
