I've got a mix of hens, my buff orpington went broody in July & molted, so she and 1 other hen have continued to lay eggs sparingly through December & January. The other 11 mature hens have been molting and no eggs for 9-14 weeks. They're slowly coming back though, with 2 eggs now from 1 easter egger (1st in 10 weeks), but not the other who is still dishevelled looking. Also 2 eggs from my Russian Orloff - 13+ weeks for her, and now today an egg from 1 of my copper morans & an egg from a silver laced wyandotte (1st in 9 weeks for both of them) There really is no hard and fast rules with these birds, but I have noticed something which I think I've heard others here say before: keep an eye on your rooster. He's a very good indicator of what's going on with your hens. He has been particularly virile in the last week, and a day or so before the eggs started showing up, I spotted him courting a few of the hens that have started laying again. It caught my attention, because there hasn't been much going on in the romance department lately with all these half-naked cranky hens squawking don't touch me! (Poor guy).
