I have been reading this page http://www.freewebs.com/professorchicken/timelineofachicken.htm, and it says that the first molting happens around 6 months. Well, I've been waiting, waiting, waiting, watching, watching, watching, and the girls didn't molt until this winter starting in November when they were 18 months old! I have 2 black ostralorps, 1 buff orp, 1 wyandotte, and 1 bard rock. Could I have missed their first molt? I feed them my own mix of seeds and kitchen scraps, and mealworms, and they free range in the summer, and they have all steadily layed until this winter - except the wyandotte who went broody for a while. And we live in Minnesota, if that means anything to this... Thanks for your insight!
