I did basically the same thing. I used a ratchet strap, stuck a piece of screen in the entrance to keep them in and got my dad to help load, and unload them from the tractor bucket. I kept them as level as possible while in the bucket.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
