I have 6 hens in their first laying season. I've been getting about 4 eggs every day for the last few months until two days ago when I haven't found any. My birds are 100% free range so it's possible, they moved their nest on me. It is common for everyone to stop laying at the same time and this early in the season? Am I being naïve and need to just put on my hiking boots and find their new nest?
