I have four Buff Orps who are a few weeks shy of their first birthday. Laying has been fairly regular, 3-4 eggs per day, with some slower periods of 2-3 eggs/day over the winter when it was really cold. The past week or two, production has dropped to nearly nothing. I have one hen that seems to be my only layer, laying maybe 4 eggs per week, which is down. Another hen is coming off a broody spell, so her lack of laying is accounted for, but the other two are just not laying at all. (The eggs are slightly different shades of brown, so I know who lays what.) I expect the Broody to begin laying soon, as she no longer acts broody. What gives with the others? Nothing has changed. Same layer pellets, same treats, same free access to grit and calcium. The weather is getting warmer, but it's been gradual and hasn't been uncomfortable until today. They're spending more time loose in the yard, but it's always supervised and in the evenings after laying should have occurred, and even still, they've been known to go back to the coop to lay, if they need. They are all acting normally, eating, drinking, roosting, dirt-bathing. There doesn't seem to be a significant amount of feathers around, and I always thought molting occurred in the fall? It's like they're just on strike. I don't suspect egg eating, because I am getting one most days, and very occasionally 2. Is this just something that happens sometimes? If it's worth anything, my brother also has chickens from the same hatch last year, in similar conditions, and his production hasn't dropped at all.
