Also, the eggs will get bigger as time goes on. When my first batch started laying one of our bantams laid an egg the size of a marble! Now hers are more golf ball sized.
My chickens turned 1 year about a month ago. Do you think that their eggs are now as big as they will get? I have BOs, BRs, GLWs, EEs, Delawares, and one Cuckoo Maran who only lays small eggs. The others lay medium to large sized eggs.
