I bought 25 cornish X rocks and have lost 2. I found blood in the stool and treated that and no more problems there. Now i have 3 or so that i have seperated because they cant seem to walk and when they are laying down they dont seem to have any balance. I have to pick them up and hold them at the water or feed to make them eat or drink. Feeder and water is next to them but they wont eat unless i put thier beaks in the feed or water. They are on antibiotics with probiotics and electolytes. Anyone seen this before?
