Thanks. I am in MA so they are pretty cold hearty breeds. We have been having gloomy weather so not much sunlight but days are getting longer. I have had an EE, an Ameraucana (pure not EE), an OE, and a brahma stop laying. The Brahma is the one that has laid pretty much the entire winter with only a short break so figured she just needed a bit of a break. Think she even laid some during her molt this year. She will be 2 in April so her 2nd winter and she laid her whole first winter as well.
If it helps, my brahma stopped laying completely by mid October, they had been laying like champs up until that point. And mid October is not cold (by normal people standards) here, so I can't say that the cold played a role for them
