I took pics of this little guy yesterday and all was fine he was perky and his comb was bright red. I went out today and noticed him in a ball all huddled up all by himself so I went over to pick him up. He didn't want to move at all and barely opened his eyes. His comb has turned purple instead of red. I took him to an isolated pen and gave him feed and vitamin and pro biotic water. I wormed everything about a month ago and haven't noticed any runny poo or blood in the poo either but with him isolated I'll be able to tell better about that if he makes it. The feed store isn't open today but can get meds if needed tomorrow. Any idea what would come on so suddenly? This is him yesterday on the right I can get a pic of him today if needed.
