So, this morning, I went outside to feed my chickens. I went out and found one of my roosters sitting in the corner. I tried to get him to move, but he just looked at me. He couldn't stand up, and he could barely control his neck. I put him in a crate with a light and some food. I left for 10 minutes, and when I can back, he was dead. Can anyone tell what what happened and how to prevent it so it won't happen again. Please help! I am like crying my eyes out right now.
