Hi, there is a wild squirrel approx. 15 weeks old sitting in front of the tree on the ground in the sun. I noticed as I approached it, it just sat there instead of running. It appears as if maybe it has a head injury but not sure. I threw it a hazelnut to see its reaction and it grabbed it and was able to open the shell but kept falling asleep while eating it. I tried to get closer to it and it would crawl away each time just enough to keep its distance. Right now it is on the ground in the sun. I'm worried the fox will get it if it stays on the ground. Is there anything I can do for it? I do have lots of prednisone if needed. Thanks
