We have 2 Orpingtons who lay HUGE eggs. Then we got a golden laced wynadotte who always lays tiny little eggs (through one season so far.) We thought it was just what she was like. However, we now have an austrolorp who has been laying for a week and laying tiny eggs. I realize she could increase her egg size, but because we have another tiny layer I wonder if it could it be something we are doing? the orpingtons were older when we got them. They all eat lay crumbles with supplemented calcium, a little scratch at night and very occasional veggie scraps.
