I have raised a couple pigs.....I would not put them in with chickens. They try to bite everything including us so be very careful when you do attend to them. They should be bought in spring and butchered about 6-9 months old. I would have to say they are a heck of a lot cleaner then cows the pigs I raised actually go to the bathroom in a specific corner and of course that area stinks but the pig itself did not smell to bad actually a pretty clean animal. They love water and they can't sweat to cool down so you need to have a pool or something with water in it in the really hot weather.....I had a well in the pen in the middle and I would fill it with water or let the sprinkler run that way and mist the area.
It is better to have more than one pig I would say 2 for your first time.....it is competition time when it comes to food and that is what you want is to fatten them up for meat. Oh mine loved milk and bread....I heard they love yogurt....all kinds of fruits and veggies. My pigs love an egg just throw the whole thing in there it will eat it shell and all.
I raised one pig each time I did and were just fine. The fencing I used was hog panels....I would bury them about 6 inches into the ground....you could get them a nose ring to which stops the digging cause it hurts I personally did not use it and would not cause I think it is mean to stop them from doing what they naturally do that is their whole life besides eating and sleeping.
As far as best meat pig.....really not much difference you can butcher any pig and get bacon/sausage etc. but if you want a lot of bacon you want a long pig I was thinking it was canadian yorkshire this is your pink pigs.
Research some stuff about pigs on line by googling it.....here are a few links I just looked up....also ask around when you see ads on pigs ask questions if your to much of a bother to answer them then move on....ask at your feed stores too.
