It seems like every time my chickens start laying consistently it ends. They will all lay everyday for a few weeks then a few or all will stop laying for a while. For the last 2 months I have recieved 3-4 eggs a day from my 4 layers. This week I have only been recieving two eggs a day. I don't think anything has happened to stress them. If anything they should be happier as they are receiving more time to forage outside the run.
