I'm on day 4 in a row of getting a egg from one of my 19 week old white leghorns. Got me to thinking...how long before the eggs should change size to maybe a grade LARGE?? Also I keep one fake egg in each nest but every day they kick the fake egg out ALONG WITH all the hay I keep putting in the nest. Then she lays her egg basically on a hard board? Could they be trying to GET the fake egg out before they lay their own?
