My thoughts and experience with feed trained LMB.

Over time many will go off feed and start eating natural forage and still eat some pellets. Some (small % )of non-feed trained LMB will , as a result of competition , start eating pellets. The offspring of both feed trained and non-feed trained LMB may learn to eat pellets but they do so for a shorter time and in smaller %s. This is all subject pond conditions. Ours are very natural and don't contain high fish densities. The smaller the area and the more fish the more competition forces LMB to eat /stay on feed and the higher the % that learn to eat pellets and stay on them.
