I have noticed that a couple of days before a cold snap or a snow (way too many of them this year), my girls seem to hold their eggs. I have somewhere around 150 chickes (ages from 4 weeks to Scruffy, we have no ideal how old she is, but we keep her because she is very good at taking one day olds that some of the others reject.) The girls get added light every day. On the average we get about 30 eggs a day. But occasionally when we go to the hen house all we get is 8 to ten eggs. A couple of days afterwards here come the snow or cold. Most of the time it is snow. Even in the cold usually get our normal egg count. The low count before the snow has happened at least 4 times now. At least that is when we started noticing a pattern. I was just wondering if anyone else has girls that can predict the weather.
