Got 6 leghorns about a month ago, had 2 eggs by the time we got home. None laid for a week and a half. Then I got 1 large egg, the next day I also got a large. Then I started getting 1 xl size egg a day then another hen started laying jumbo sized eggs. I have been getting 1 xl and 1 jumbo everyday for about a week now. This morning I got 2 large the xl and jumbo one of the large is a cream color though. Why are they laying different sized eggs and now a different color? All same breed chickens
