I have 15 birds ranging from 1 to 2 years old and I’m presently getting 9 or 10 eggs a day. Was almost as good through the winter. Northern Ontario. Most are non production birds and not really the best conditions right about now. Most of them are molting too. I’ve never had a problem with egg production although I usually have a pretty good turnover every year other than this year. If you have older birds I could see why production isn’t as good.
