I have 5 hens, 2 are too old to lay, the other 3 are roughly two years old. I have a timed light that goes on around 2AM to make sure they get plenty of light. They quit laying in early December. I noticed they seemed to be molting so I turned the light off until last week and now have it back on. Still no eggs. Does anybody no why they would all quit laying at the same time? Even if it is age related (meaning the person who sold them to me lied about their age, I can't imagine that they would all quit at the exact same time. Any help would be appreciated.
