I purchased (2) 50lb bags of chopped corn at Tractor Supply. When I opened the bags and poured the bags in the 55 gallon drum, I noticed that there was a little mold on some of the corn. I took out the mold and it was only about a handful of mold from the entire bag. I threw the molded corn away. I put some of the chopped corn out for the chickens to gobble up but there was no mold (or I thought there was no mold) on the corn that I put out for them. This morning about 6am, I went to the coops to let the chickens out and noticed that 1 of my Buff Orpington hens was dead. She had fallen off the roost and was just laying there. There was no visible signs of trauma and no signs that a predator had gotten in to the coop. The only thing that I can think of was maybe she ate some of the molded corn and died. How much of the corn would she have had to eaten to die? I know that there wasn't any more mold in the corn. Would a VERY small amount of mold possibly kill a chicken within 24 hours? She was the only hen that died and I have over 100 chickens. Could the entire bag have been contaminated? PLEASE NOTE: When I called Tractor Supply they did tell me to bring in my receipt and they would refund me the money for the feed. I got to the store and I got 2 more bags of corn but before I left they opened the bags of corn and both bags of corn had mold on the bottom. They opened more bags of corn until they found 2 bags of corn that had no mold. Please make sure that you check your feed before feeding it to your animals.
