I have an Australorp that started laying at 4 months 1 week. She laid 3 eggs and then stopped for about 3 weeks. She turned 5 months on June 25th and is now laying 1 egg a day. Small eggs but they will get bigger as she lays more...I hope??? I have a total of 8 hens and can't wait for the rest to start! The waiting part is the worst but worth it!
