I don't think its normal. best I can figure is he had a rough day or few days. He may have had a close call with a predator. Maybe he made it to your place and you were shooting at him, I don't know. I think he endured some form of stress that had him exhausted. Could be his food gathering skills are not where the need to be yet in the wild and he just burned to many dang calories. He was literally falling asleep with his eyes open and on his feet. I have not let him back out yet. The wife wants me to wait until I have time to sit out there with him for a half hour and make sure hes acting normal again. I am also thinking of dying him safety orange. You wouldn't shoot a safety orange squirrel would you?
