Hi I have a flock of 6 that are all between 6-7 months old. They haven't started to lay yet, and I'm wondering if that has to do with the cold. I live in central Texas though, so "cold" to me is not that cold. All are egg laying breeds, so will they start to lay soon or do I have to wait until the spring time, when things warm up a bit more? Any knowledge would be much appreciated.
