Beside what I have already written concerning homesteading I would like to add the following.
(1) Make sure that you select the area you are comfortable living in.  Do not move to some part of the country just because it sounds good.  Or someone else suggests it would be a good place to live.
(2) Do not try to raise to many animals to soon.  Get a few at a time and grow as you learn.  This is especially important to someone that has never experienced raising animals before.
(3) Be sure all of your animals have adequate shelter.  If you live in the south as we do, the housing can be different than up north.  But you must make sure your animals, chickens and rabbits can be kept dry in wet weather.
(4) On chickens, we have found it is better to start with baby chicks.  You are less likely to bring in some disease from another persons flock.  Also I would suggest you start with the breed called Sex Links.  About 10 hens and one rooster will keep you in eggs and you can raise your next young chicks yourself by letting one hen or two hens set each spring.  I like to place only 10 eggs under each hen and usually get from 8 to 10 baby chicks from each batch.  We also have an electric brooder we hatch 42 eggs in every 6 weeks.  But we sell chickens and also sell eggs.
(5) My advise on rabbits---------------Don't get started.  Unless you want to eat a lot of rabbit meat.  I had a friend that had one buck and two does.  In one year time he was begging people to take the young rabbits free. This is also one animal that requires good cages (separate ones for each doe and also the buck).  And that means that each time there is a litter and they get breeding size, they also require a separate cage.  They must be kept cool in the summer months.  They tolerate the winter months real well though.  If you do want to raise rabbits though, I would suggest going to a local library and reading all books you can on their care.  I have raised them and they are great fun to raise.  They are just not very profitable. They are also a very tasty white meat.  There are so many different breeds of rabbits that you will have to check which ones you would like to raise.  Do you want meat rabbits, show rabbits, or Angora rabbits for their wool?

The one thing I would tell you to avoid is being in debt when you make the move.  There is no greater joy than living off of the land and raising your children on the farm. But it can be very discouraging when you are having to work an 8 to 5 job and run a farm also.
