That white speck in the opened eggs is probably an undeveloped ova(yolk) that the rest of the eggs was formed around. ISA and Comets are high production breeds and they are more likely to develop reproductive disorders. Not much you can do about it.String is gone, 24 hr. feeder full of Kalmbach layer feed, she started laying the same time as the others and all the same size as the others, I get 5 normal and 1 mini every day, the photo shows all but 2 that she has laid. The tiny basket is full of her eggs plus the one on the counter for size comparison. I bought ISA Brown and Golden Comets so she's one of those.
