Hello we have five wonderful hens that have lived with us since May. One Rhode Island Red, two Aracana's, and two other chickens I have yet to find names for. All were consistent layers until about October and as of now we have not had an egg since then. They have been vet checked and are in good health, we have not changed their food, and they get fresh water twice a day. I have been trying to troubleshoot and hope someone here might have some ideas. Thanks!
