The KEY is having someone (parents in my case) that will take care of the livestock while you are away.. and take care of them right.. It doesn't matter if you have 1 or 100. In my case, I went to Juco, about 100 miles away, but since I was on the judging team, I only got to come home for the weekends, maybe 2 or 3 times a semester.. I went to the university, about 5 hours away from home, and made it home even less, for it was far too expensive... My parents told me they would take care of everything for 4 years, until I can get a "real" job-- and start doing it myself again. I have that real job now, and don't start until the end of Feb.. but atleast I can lamb out my own ewes, for the 1st time in 4 years!
Now on the other hand, I have a cousin, that has had her own livestock since about 4th grade (or so) She's now a freshman in HS. I know her parents wouldn't do the same thing, as they have no desire to help her out now... In her case, if my parents don't do it, or don't push her to go to college.. then she's not going, or if she does go.. the livestock are getting sold off.
I just bought a flock of ewes from a similar story, as the folks youngest kids were headed off to college and they wanted to sell them...
I suggest that you sit down and ask/ talk this over with your parents, ffa adviser, and whoever it is that you are currently keeping your steer at's house.. They will be able to better give you sound advice and knowlege about what you are asking, rather than a bunch of people you have never met, don't know the names of.. and just are known as a screen name/ picture.
