What is wrong with my chicken? Loss of balance, leaning against things to stand up

[fruitveggirl]

It doesn't have to be wet to get mold in it. I have used a bag of feed kept in a metal garbage can in my shaded coop before for days, and suddenly one day noticed it smelling odd or chemical, then saw a blue green color. Scratch grains are even more likely to get moldy, as I have discovered in hot summer weather. It is just something to be aware of. Here is some good, but long reading about Mareks, and the things that can look like Mareks: https://www.backyardchickens.com/articles/the-great-big-giant-mareks-disease-faq.66077/

Thanks. I appreciate it.
