OK, I have one for everybody! My two game hens laid brown eggs all spring, and then began their molt and stopped laying. When they resumed laying a week ago, the eggs are now nearly white, or just barely tan. I'm feeding them pellets from the same company I fed crumbles, and they also get oyster shells. They live in a tractor which is moved about 5 times a week to a new area of the yard. The shells are not weak at all; in fact, it takes quite a rap on the corner of a countertop to get them cracked. Are they like flamingoes? Do they need more brown in their diet? More iron, perhaps? More of SOMEthing???
