I have 2 Red Sex Links and a Tetra Tint that are currently 9 months old. They were laying great till the beginning of November. They stopped for a couple of weeks and then I put a light in their coop to lengthen their days. They started back up after about a week. Then on Christmas day they stopped again even with the light. The only thing I can think of is that the PVC automatic feeder I made wasn't being very automatic and maybe they weren't eating enough. I altered the design a couple of days ago and it seems to be truly a continuously available feeder now. My question is how long should I expect it to take before I see eggs again?
