I have one alpine and three boer/nubians that share a circle pen that gives them plenty of room to run. In fact, hubby built them a teeter totter which they love! However, this pen does not have a roof and with the upcoming occasional rains and dampness, I want to give them shelter as well. We put up a tarp which should have worked, we thought, however the goats think of it as a toy and possibly a trampoline! What have you all done for your goats? I obviously don't want to break the bank on this and even see that igloo dog houses, as some on Pinterest suggested, are pretty pricey when you're buying for four. Plus, I would think they would want to be in the same one? Any suggestions would be great!
