I have raised chickens for the last 10 years, with very little issues, minus a few predator problems . This last month we noticed one of our hens was sick, I brought her in the house, treated her with natural remedies but she died a few days later. I started the chickens on bread and corn ( i read that could start them laying in the winter as they had stopped laying for the last few months even with a heat lamp). About 2 weeks after the first hen died, I went out to the hen house and another hen was dead. I wasn't too alarmed because this was an older hen ( she was 7 years old ) but she hadn't been showing any signs of being sick. Yesterday, two weeks after the second hen, a third hen was dead in the hen house. The only one that seemed sick was the first one. They all seem to be healthy. But now I'm freaking out. After the second bird died I completely cleaned out their house and bleached the floor and nesting boxes, waterbowls, and feeding dishes. I saw another post on here similar and someone mentioned worms. Could that be it? Just seems odd to have them die 2 weeks apart. Also should I throw the eggs away ? Could they be contaminated ? I feed them a organic soy free lay food, plus they eat a ton of kitchen scraps. I added new birds to the flock last spring so I don't think that's it. Im going to go put garlic and ACV in the water while I wait for a response !! Please help!
