In August, my young hens started laying and we were thrilled! Out of the 10 leghorn hens that I had, I was getting 7-8 eggs a day. My brown layers started laying late in September and I was only getting 3 eggs a day out of the 10 of those and some days none at all. Last month (in October), my dogs got into the fence and killed two of my leghorns. Right after that, they stopped laying and it has now been weeks since I have gotten an egg. I have looked around for a secret nest and have not found one. I am feeding them layer and they are free range. I have a light in the shed for them, but I live in SW Michigan and it has been very cloudy this month! Could it have been the stress of the dogs, or not enough light to cause NO eggs? I have raised chickens before and in the winter months have seen a decline of eggs, but not completely stop, especially this soon! Any suggestion as to what the problem could be?
