I have been watering our pig in a bucket, which he dumps no matter what I do to secure it in the pen. It also gets filthy dirty and I am constantly changing it. I have checked out waterers online and the only ones I can find cost like $500 and I can't pay that for 1 pig. Do you have any suggestions on what I can do? He is being kept inside my barn in a pen. We found this pig and don't have adequate fencing for him at this time.
