Our Easter Egger who was born on 4/8 laid her first egg on 8/22. We saw her in the nest box and took it out when she left. Since we were watching, we know she laid it. Now six weeks later, and we've never found another egg. We've searched outside of the nest boxes just in case, we've watched her carefully throughout the day, but no more eggs. Some of our others have started laying, but they are white and brown eggs. She seems happy and healthy so I don't think she is an internal layer. Does this just happen sometimes? We keep hoping she'll start laying again. She is turning six months old now. Any ideas?
