I am starting a pig farm to raise pork to sell
Awesome!  Farming pigs is a  branch of animal husbandry!
Yes and i am new to it but plan to be a ethical humane organic farmer!
That's great! At one time pigs were kept in small numbers - how many do you plan to have?
a couple of hundred and I plan to free range them over 300 acres
Wow, you have some big plans!  In some places there are farms that have thousands of pigs!
