Hi! So I have four hens that are give or take 3 years old. I have one 'nice' rooster. At first they were laying great, but now I only get one egg a week. This has been a problem since the summer when production slowly dropped. I've checked, I don't see any lice or mites (but they had them a year or so ago). Some have been molting on and off, and they kind of look a little ratty. They eat layer food or whatever it is called, it's organic. They have free choice grit, cracked corn and occasionally compost, cat food or fats (protein). They are raised in my belief pretty well, clean water, a good size coop and access to an outdoor pen and a chicken tractor. I don't see how sunlight is the problem because they have a light on for some of the day. They don't get oyster shells (should they), I have no idea if they have worms, and now I'm considering coccidiosis, but not really. One hen sometimes has a clumpy white dry past stuck below her vent and to her feathers. The eggs we do get seam pretty healthy and look 'good' inside and the shells are ok. So any ideas? Are they sick. They have been lazy for a while now, and my parents are mad that they have to buy eggs at the store now Thanks!
