I have 4.
2 are Navajo Churro and Clun Forest crosses. They are extremely docile, wonderful sheep. They are mother/son (son is fixed) and the mother is especially docile. They all get a little upset when we flip them to sheer or clip hooves and she just sleeps or eats grass upside down. I love her!

This is those two in the winter. They are much cuter sheered, but I can't find pictures at the moment.
And these are the other two, I can't remember what they are a cross of.

They're cute to watch, they do the stiff legged jumping/running thing and it's hillarious. I wish I could get it on video one of these days. They are less skiddish/shy than the other two (it's a breed thing). They prefer to have grass and lots of water whereas the other two are a desert breed and they prefer hay and don't drink nearly as much water.
And as for wool, our old shear-er used to bring it to a school for the blind, and when he didn't our neighbor spins so she used it (made me mittens once and I love them!) And this year my boyfriends mother took it and she is going to have it cleaned and spun and use it to make something. So, as far as I know it's really good for spinning!
