I have a pullet who is about 9 months old, and she has been laying faithfully in her nest box nearly every day for the past 3 months. This week, she has not laid 4 out of the last 5 days. She doesn't appear to be molting, and is acting otherwise quite normal. What's going on? Is this normal? Is it possible that she suddenly started laying in a sneaky place somewhere else? Or is it normal for them to just take a hiatus for no apparant reason?
