Good Heavens, man. Don't waste your hard earned money on alpaccas. Get thee to the local sale barn and purchase some sheep. They will keep the acrage chewed down and eliminate the need to mow. If no sale barn is nearby, look up the Farm Bureau in the Yellow Pages. Go to their office and ask to see a copy of their weekly newspaper,,, flip to the back and scan the classifieds... you may find sheep for sale there. If this scheme fails,,, go to the Extension Office, ask to speak with a "Livestock Specialist". Bare your soul to the Specialist, and ask advice in locating the sheep.
