Growing Piggers on Farm Fresh Fodder

The piggers have been here since March 16 and we fed one full week of starter since that's what they were on.  Then we switched to 1 full week of grower and threw in some of the fodder, which they weren't too interested in.  They have been kept on full feed, anytime for the first two weeks.  We are now well into the third week and was so bold as to let them run out of the grower grain.  Not real interested in the fodder until the second day - then there was a feeding frenzy, alot of pushing and shoving and growling at each other.  The third little pig always lost out.  So at 3 1/2 weeks we are feeding only fodder in the morning, but in two different places, so they all eat.  They are devouring it.  We feed half a biscuit at 800am and the other half at 12noon, in the evening we just feed 3 lbs of starter grain.  We don't want them to be stressed and hungry.
