I have a silkie rooster, I believe he's about 8 months old. Last week, I noticed him shaking but it was pretty cold so I gave him some more straw and didn't think much of it. Today I went out and noticed he was still shaking and it isn't that cold anymore. It's not a constant shake, it's more of his whole body'll shake for a few seconds, stop for a few seconds, then start again. I took him inside the house to see if that'd help but he was still shaking so I put him back out. I also noticed this brown crust type thing around the edges of his waddles. Touching it doesn't seem to bother him. I'll try to get pictures of it tomorrow Does anyone know what could be wrong? Other than that he seems perfectly fine but I'm still a little worried about him.
