I'm relativly new to chickens. We got three golden comets last Sept. We consistantly have gotten 1 to 2 eggs per day since. All of the hens are the same age, they were a year old when we got them. I just thought it was caused by molting that we have never gotten 3 eggs per day. About a two months ago we started seeing a third egg smashed in the coop maybe once per 10 days. Now, a couple of weeks ago we started seeing a third egg maybe 3 to 4 times since that is the size of a malted milk ball. When you bust it there appears to be no yoke. Any ideas? Is this normal or is there a problem.
