Some will come sooner rather than later (spring 2013 I'm planning on getting my first couple sheep or goats, possibly some rabbits as well).
Some animals are more expensive than others (cattle and bison can cost $1000+. Goats, sheep, swine and donkeys are in the $150-$500+ range. Rabbits and poultry are generally $5 to $30+).
Some breeds need lots of attention, others can forage and birth on their own with great results.
What kind of animals do I want to raise?
How hands on do I want to be with my animals? How hands on CAN I be?
Do I want pasture/foraging breeds or barn/feedlot breeds?
Do I want breeds developed for commercial industry or heritage breeds?
Will any heritage breed do or should I focus on finding Canadian heritage breeds?
Am I only keeping animals for my family (and friends) or will I be selling meat, milk, eggs, fibre, breeding stock, etc?
Lots of questions that need answers. Some are even pretty easy to answer. Others, not so much.
