NH, one thing I learned after being raised on a homestead with cows, goats, chickens, etc., and then researching for years while hubby was in the military...researching is only good to a point. The hands-on is the make or break. Lots of things looked good to us on paper and with my childhood memories, but did NOT work for us at all. Guineas, for example. Loved them as a kid, hated them on our place. I love geese and muscovies, but again, they don't work on our place. Tried them both out. Even though I was raised handmilking cows, it's only been after 10 years on our place that I decided to give a go at raising meat calves. Even a nice, gentle cow can hurt someone, and not even notice, just because of their size.
All that babbling is to say...make sure you get some apprenticeship time working with cows before you buy one. Enough that you know you want to do all that is necessary. Then you'll know if that's what you want. But I'm a little gun shy. You would not believe the notebooks full of research I did over 20 years of military time, waiting until we got our place. There are still a few things I'd like to try, but there are LOTS of things that I tried and that just did not work for us at all. Lots of money and time was invested because I figured all that research made me knowledgeable. But it's not enough without the hands-on. I should have known better, too. I'm a biologist, for Pete's sake. I know all the research is preliminary, but I somehow didn't apply that to myself.
Not trying to be discouraging; just realistic. This forum is so enabling and Rah! Rah! Rah! that it's easy to get in over our heads. I'm learning self-control here! Hard learning curve, too!
