I'm having a bit of an emergency! I bought a 50 on bag of feed (mannaPro layer crumble) and filled my chickens auto feeder. They ate one container of it, when I filled it again I noticed they weren't doing very well.. Well they never touched it again. I have given them cracked corn and they're eating that but I had many chickens lose weight drastically and die, one is paralyzed through his feet and I now have one of my Japanese bantam chicks going down. I just woke up and have found two more of my hens dead this morning out of the hospital cages. Chickens that were running around, fat and happy are now dropping like flies and as thin as a rail! I don't know what to do! I have bought a new bag of feed and offered but they still won't touch it. I had bought a pair of pintails a week and a half ago, the hen got killed (by my mallards) and the drake started these same symptoms and passed three days later. I don't know what to do, any help would be greatly appreciated!!
