Try not to over commit yourself.
Its very easy to commit yourself to a lot of horses when you have a job. And while you might get the job try not to put yourself in a position where you are so reliant on a job that you can't quit, or can't live without it. Jobs such as waitressing can be very insecure.
If I were you I would look at it logically. Either you want a young horse or you want a seasoned horse. Sure, it would be nice to have both but choose which one you really want and work towards that. Save your extra income so that in the future you can look at two horses with a really good, perhaps year long safety net.
I don't know about Boots or April or Fancy but choose the one who you like best and who best suits your purposes. With a young horse you may not be able to ride for a while, and a lot can happen. Especially if you are working a fair bit, you might appreciate a horse you can just get on and ride, rather than a young one you have to work consistently everyday. Weather doesn't cause aggression, provided you nipped it in the bud it could be fine.
I've had multiple horses, so I'm honestly not too worried about it logically. As for waitressing, I did intend to wait to see how promising the job was. Many have told me though, that slow nights can still bring $100 just in tips, and a good night is $700+. If I can just get one half-decent night a week, I'd be able to afford it fairly easily and still help out with bills.
It may not cause aggression, but it always seems like cold fronts make horses frisky around here. He never got that mean before. I've been ran over one too many times, so... this is how it got worked out.
He flattened his ears, turned his head, and really tried this time to bite. I popped my hand on his neck, flat palm and just hard enough to make a sound, and pushed his head away from me while tell him no in an unhappy tone. That was when he decided to spin and tuck his butt before kicking - not too high, but I did also move out of the way and shout at him. Once I was out of the way and had some space between us for a second, I came back and held my hand out. When he pinned his ears, I spoke a little loud and angrily, "no" and stomped my foot. He stopped trying to bite and ended his ear pinning, but he did try to kick me once more. He didn't act afraid, just not in the mood, honestly.
I'll be visiting today to see if he'll be in a better mood with better weather. I'm finding it a little difficult thinking of ways to discipline this colt without seeing risks in anything that comes to mind. Help?
