My mother raised three children while taking care of 100 cows by herself. Now I am in my 30's and I help her. My husband is also not a cow lover. I married a city guy and he helps out around the place with anything but the cows.
We currently have 72 cows, so don't worry that a woman can't do it.
I do have some advice and if it is repeated I apologize, I only skimmed the other posts.
1) Find a good vet. This is critical for either a man or a woman just getting started with cows.
2) Calm your cows down and be tough culling for temperment. You'll thank yourself for that. There's enough nice cows in the world let someone else deal with the nuts.
3) Whether you name your cows or have their numbers as their names make sure they know their names.
4) Don't start out with older cows unless you know where they are coming from and how they've been treated. It's easier getting them young and training them to do things your way. I know a lot of people probably won't agree with me on that one but if you are out buying 5 year old cows they can come with baggage so check them out carefully.
5) In every herd of cows there will be a boss, know who she is and make her your best friend. A good boss cow will make your life safer and easier in so many ways. Of course you should always be at the top of the herd for pecking order.
6) Never forget that a cow in labour can act much differently than they normally do. So always be aware.
7) When you are out with your cows talk or sing to them. They'll get used to your voice and it will become calming to them.
8) When you hang out with them chew gum. Cows understand then that you are relaxed.
Your not nuts, I can't understand people who don't want to be around cows! ;-)
