My son who is 7 has decided he wants some pigs so was thinking a couple to start with so thinking buying weaners and finishing and getting killed at local butchers then selling to family neighbors etc. Any ideas of best breed how much we should pay what to feed (can I make feed myself we have cereals and soya etc in stock. How long will they take to fat what weight to kill at is there anything else we need to sell meat. He is very keen to make a profit
