For what it's worth -
Old Farmer's Almanac says that we're in for a colder winter than the past several ones. I'm glad the weather is finally going to get cold enough to kill off all the nasty bugs around here (mosquitos, fleas, ticks, etc), but it's not gonna be easy on the outdoor animals. No insulation in the coop, but I'm stringing out a heatlamp for the brooder babies (6 - 5wk olds), and the rest will get to "share the wealth".
All 11 of my hens have quit laying as well. I get 0 - 1 eggs a day where 4-6 were the norm, and 7 or 8 twice a week or so. 5 of my hens are Production Reds, 3 of them had just come into lay. Dependable for an egg a day. The ones that are still laying are the "two old biddy's" - the two oldest PR's, and a Barred Rock. My broody leghorn had resumed laying after raising a clutch, layed about 10 days, then stopped completely.
A friend and neighbor has 50 hens, and she went out and had 3 eggs! At first she thought that someone had been stealing eggs while she was at work, but the next day, while she was home, she got the same results, 5 eggs.
The man down the road has pulled up his "Eggs - for Sale" sign from his yard, so I guess he's having the same issue.
Winter is definately on the way, and it may be a Bumpy Ride!
