Hi and welcome to CT. Brute is right about getting them used to you and teaching them from the start where their food and treats are coming from. Getting them accustomed to hearing you call them, and feeding them, will make them alot easier to handle in the long run. Make sure when you do call them, that you give them something. Feed, cubes, fill the mineral, a few flakes of alfalfa hay.... something as a "reward" for coming.
I am in Va so can't offer much advice as to breed. Here, "black" is what sells. We happen to like red cattle too, but take a beating at the sales on them. It doesn't seem to be near as bad way up north, or down alot further south. Since they are not going to be something you are depending on to "make a living" then get what you like to look at.
There are idiot cattle in every breed and color. From what I have read, the gerts and anything with some Brahma influence tend to be very protective type of cattle. I have read some people who talk about how aggressive angus are, and just don't see it in ours. I see more "high strung" attitudes in limousin cattle here. We have a couple of red polls and they are very calm types; but they are so maternal that they will bellow for weeks after you take thir calf instead of a couple days. Not aggressive with us, they just don't like to "let go" of their calves.
Good luck. Right now cattle prices are quite low. It is hurting us cow/calf producers. But there are decent buys to be found so it's a good time for you to be getting in.
