Please help I don't know what's happening! I picked up 26 broilers I had ordered on Tuesday 6/13 everyone was alive and seemingly well. There were a couple that were a little lethargic but I just figured it was the trip. I put them all in the brooder with hay substrate, water with acv and feed (nutrena meat bird) over the next 2 days more seemed to be lethargic, not eating and just laying under the heat lamps. I lost my first one on Thursday night. Then 3 more on Friday and so far 3 more today with more to come. I've seperated the ones that look sick. I've done fecal exams on them (nothing found) started corid anyway. I've been syringe feeding water and gave them some poly vi sol. They just flop over on their backs and die What is happening? Is it something I'm doing? I've raised chickens and turkeys but these are my first meat birds. Thanks in advance.
