My kids are excited, the new pigs came yesterday. One boy and one girl. Of course, my oldest daughter got to name the girl and my oldest son got to name the boy. They are 6 and 4. So now we have new temporary residents, Bacon and Penelope! The pig feeder I have them on is 6.50 per 50#. Should I just buy bulk and mix my self of is this the best way to go?
