FarmVille Livestock Mystery Crate: What's inside?

As part of Zynga's attempt to make people care about the Livestock Pen in FarmVille, which, admittedly is a little hard (don't we already have dedicated storage buildings for both pigs and sheep?), it has released a Livestock Mystery Crate in the game's store containing six animals that can be stored inside your new pen. Now, the Livestock Pen can also store animals like goats or llamas, but unfortunately, only two items of these six re-released animals isn't some form of Pig or Sheep. Here's a full list so you see what I mean:

Alpaca
Babydoll Sheep
Miniature Goat
Teacup Pig
Welsh Mountain Sheep
White Ram

Each of these crates costs 20 Farm Cash, and they can be purchased from within the Decorations tab of the marketplace, instead of the Animals tab like you might expect. Remember, while you are guaranteed to receive one of these animals when you purchase a crate, you aren't guaranteed that you won't receive duplicates the next time you purchase one. That being the case, you'll want to really make sure you don't already have some of these animals already on your land before making a purchase, to ward off any unneeded extras. If you do want one of these crates, shop fast, as they'll only be around for five days.

Do you already have all of the animals inside the Livestock Mystery Crate, or will you purchase some for your farm this week? Which of these animals are you hoping to find inside?
