Well just to give my opinion 2 of my girls first egg was a large double yolker. The remainderof the eggs were small and sometimes chalky. I have one layer 3 gorgeous eggs in row and the fourth day layed a chalky one. So I figured she wouldn't lay today and I was right. She didn't. They are young so it takes time for them to sort things out. I have another that layed her first 6 days ago and hasn't layed one since. It will work itself out I'm sure.
