I have 12 hens total. 6 PR(2yr old) and 6 BJG(1yr old). I am only averaging 5-6 eggs per day. Sometimes as little as 4 to as much as 8 eggs per day. I feed Dumor 16% layer crumbles mixed with oyster shells(lightly) and scratch grain or cracked corn just as a treat/filler with the feed. Is there a feed that has more than 16% or something i can add to the dry feed to boost protein and gain more eggs? My BJG hens don't appear that they will be laying X-Large eggs. Instead the egg sizes are medium to barely large at best. Will their eggs ever get bigger? Thanks alot for any help i can get.
