edit: reworded to be more clear I have 7 hens that are aged 21-23 weeks. They have not yet began to lay any eggs and I was wondering why. These are my second batch of chickens, my first batch are all adults now, 10 months old and they are laying pretty well. Am I just being impatient with my 21-23 week olds or are there factors that could slow down their laying process? I've heard the cold can make them stop and many won't start again until Spring. The weather here is pretty mild and none of my other hens stopped laying. Are they just late bloomers or will they only begin to lay come the Spring time?
