How many weeks old should you release a healthy flying squirrel? Mine is about 14 weeks now and I'm in northwest il. and winter is setting in. I'm going to my brothers house in Texas for thanksgiving. I can leave him with my brother and his wife(she's a game warden) I'm assuming she'll know where families of flyers live in the state park she works in. I really want to keep him but his happiness is more important than my selfishness. Thank You in advance.
