It is convenient to be able to rent when you just need something occasionally. Especially when you are not real particular about the size or condition of what you are renting. I am not sure a ram falls into this category.
I am not saying all rental stuff is of a lesser quality. Sometimes you get a rental car at an airport that has less than a hundred miles on it. It may not be your favorite color but it has all the necessities, usually GPS (which I don't have), and smells like a new car.
So if you are in the market for a ram (as I am) you might want to check out the rentals before you buy. That way you can save yourself quite a bit of trouble and send him home when you no longer need him. Only problem is you might have a hard time finding the breed you want, the color you want, the temperament you want, etc.etc. but you might get lucky.
A few days ago, I emailed a woman I know who has CVM sheep that I like the characteristics of. She is on vacation but emailed me back and said she has a ram for sale and will call me when she gets home. Will she rent me a ram? Don't know?
I am really getting excited about the next phase of sheep farming which is having lambs born on the farm but it is alot of responsibility. I am going to improve some of my fenceing and move a gate whether I rent a ram or bring one here to live so that will keep me busy until the woman gets back from vacation.
