Well, it's good that he's separated from the flock anyway. If there's anything contagious, hopefully it won't spread to the rest of the flock. And, if he's in a weakened state, the others are likely to peck at him. He just might perk up. I would get him warm and dry and inspect him carefully to assess his condition. Don't punish yourself for being at work. we all have to live. These things just happen. Keep us posted!
