We feed our 4 pigs twice a day. We slop them with kitchen scraps plus excess or old milk and eggs. We also fill up a large bowl with grain (large rubber type bowl from the feed store). It is always gone when we get back but am wondering if we need to feed them more. I think they are around 75 lbs (maybe 4 months old? Gosh, I can't remember tonight) and eating a 50 lb bag of feed every day or day and a half. Are we feeding them enough? Should it be more of a free choice thing with the grain?
