I just started with chickens this year. I have 6 hens that are 23 weeks old. The three white leghorns are all laying regularly, 1/3 NH Reds are laying, and 1/2 of the Dominiques started laying. She laid about 4-5 eggs in a 2 week period and stopped. I added artificial lighting in the mornings to make sure they get at least 14 hours of light, but still nothing. Any ideas as to why she stopped? I assume my other non-laying girls should start any time... is that right? Thanks!
