They're more difficult than you'd think and they're not easy to load ,and when they get around 300 pounds they're intimidating, when you are in knee deep pig slop, trying to load them, because it just happened to pour down rain the day you Have to take them to the butcher, ... Also a big pig can and will bite off your knee cap if you tick them off.(not speaking from experience) thankfully... But that being said I've been raising feeder pigs for 5? Year's now, and I'm still doing it lol. You can feed a pig everything but citrus and not have to worry about them getting sick. Don't expect to make money on selling them to relatives, or anyone , (unless they will pay you $200/$250 a pound Live Weight... And they pay the butcher fee. Also the best idea is to buy and raise feeder pigs to butcher size, don't bother with the sow boar side of it, unless you are planning to shell out a lot of money in feed, and you have Concrete sheds to Farrow in. Those nice shiny metal pig huts they sell at farm stores, pigs Enjoy destroying them..
