I'll try to make this as short as possible....I have had 16 egg layers (golden sex links) for over a year now and a month ago we got 10 Cornish cross meat chicks. Our egg layers are free range and our meat chickens are in a chicken tractor that we move around on our lawn. I have had NO problems at all until 2 days ago. One of my hens was found in the lawn looking and acting very sleepy and lethargic. I checked her over and saw nothing unusual. We put her in a kennel by herself with food and water and within 2 hours she was dead. She never did really "wake up" just kind of stumbled and flopped around?? After she died it looked like maybe she had prolapsed a little and I figured she must have been egg bound?? Now today there is another hen on the lawn looking lethargic?? The one thing I was wondering was, when we move the meat chicken pen the hens come over and clean up the spilled grain(flock raiser) and it looks like they also clean up some of the poop! Could eating the meat chickens poop make them sick?? The meat chickens show no sign of illness. The grain they spill is minimal they can't be getting more than a handful. I have checked them for lice and mites but see nothing and I have checked the sick one over and see nothing wrong?? I would appreciate any feed back.....thanks!
