I realize twelve hours of natural light is barely enough to trigger laying. But by this time last year, I had half a dozen of my seasoned layers already laying. This year, three of them began to lay near the beginning of February, and then quit after a couple of eggs. My Cochin laid very regularly for several weeks, and has since stopped. Now, the only ones laying out of eighteen layers are my five pullets. Yes, I have been giving them red pepper flakes. The only change from last year is that they're getting fermented feed. Would that cause this? They all seem very happy and healthy otherwise. No, they've never had parasites. There haven't been any stressors. Any ideas?
