Our four hens are 9 months old and all summer we got 3 or 4 eggs a day. Exactly one month ago they abruptly stopped laying and we had no eggs for two weeks. Then after those two weeks we started getting one egg every other day. This is our first year of chickens, so could this be due to molting (we have noticed more feathers in the coop but the birds aren't looking drastically different) or shortened days or..??? Any thoughts? Nothing else has changed in terms of feed, water, etc. Thanks!
