I have six chickens that I got in March 2013. Two are white leghorns and four are ameraucanas. The leghorns are a week older, and started laying first. We were reliably getting 1 egg / chicken / day from the leghorns until the ameraucanas started laying. One day, about 3 weeks ago, we had 5 eggs. Now we are lucky to get 2 eggs. Yesterday they were both blue. Do you think the leghorns have stopped laying or are sneaking them away into a new spot?
