Ah, I had missed the corn comments. I am so thankful you were more observant than I was Haunted55!! Yes, this is very suspicious too! I would absolutely stop feeding that corn. I've also read broccoli is very beneficial, along with very dark leafy greens if you have them such as kale. Kale is often recommended for parrots suffering from aflatoxin poisoning so I imagine it would work well for chickens as well.
