My hens just don't lay eggs. I don't know if they are deficient in something or what. I have a rhode island red that is about 2 and half years old and lays about one egg a year now. I have an Americauna that is about the same age and lays in stages. She goes several months without laying anything then will lay for about a week. I also have a 9 month old Wellsummer that started to lay eggs at about 5 months old and stopped after a couple weeks. I'm just not sure why the younger one stopped laying and hasn't done anything since that one time.
