Hello, I have 15 chickens. A mix of barred rocks, Reds, and Ameraucanas. They are all now 2 years old. We use to get about 15 eggs per night even during winter because we have a light that comes on to simulate daytime and a bit of heat. At the end of last winter the egg laying slowed down during the summer a lot. Maybe 3 or 4 eggs a night and then it went down to 1 or 2 eggs in June and no eggs from our Ameracucans at all since that time. Now for the last few months, nothing at all. The reds look like they may be moulting a bit still and one of them is broody. We have had to break her a few times of it already. One of our reds got sick two weeks ago and was losing her balance. I looked in this site and found she might have been eating or drinking dirty water. We always gave our chicks scraps from our garden. Tomatoes mostly. I read that rotten tomatoes could cause issues. So I medicated them for 6 days per the antibiotic in the water for e coli? not sure if that is spelled anywhere right. My little sick girl drank a ton of medicated water, I separated her from the others by closing the door to the built on chicken run. That night she actually put herself to bed and we had to hand wrangle the others into bed. The next morning she was out with the others eating and drinking but a bit wobbly still and by day three she was back to normal. Now we have tried increasing protein a few months ago, cameras in the coop for predators, clean the coop every week and water every other day. Nothing is getting them laying eggs again. I have watched for cannibalism and nothing. The food is still the same, they eat about 2 to 2.5 cups a day between them all. I started feeding them on the ground instead of a trough. Just don't know what more to do. Any ideas?
