I have 3 RIRs, 3 Black Australorps, 2 Buff Orps & 2 "Americaunas", all 21 week old hens. Only 1 of the RIRs is laying (little bitty eggs). Since they were about 3 weeks old, they've been fed non-GMO, non-soy feed. Am I missing something I should be doing to encourage laying with this kind of diet or is it possibly the cold weather?
I know that shortened daylight hours have an effect on egg laying. I think ours took longer than "average" to start laying because they were hatched in the early fall and grew up as the days started to get shorter. they're over 7 months old now and not all of them have even started laying yet, not one did until they were 26 weeks. We just got 8 eggs for the first time today (out of 13 pullets). So, give them time, they will make it happen!
