I am currently caring for my first squirrel. When I got her, her eyes were still closed but full fur. Her eyes opened 8/23/24 so she is almost 16 or 17 weeks (all the info I've found is 50/50 if eyes open at 4 or 5 weeks). Also in all that reading and research it says that if a baby is not old enough to be released by September then you need to keep them through the winter. Is this correct? I live in Virginia, coastal area, if location/climate matters. If I do need to keep her through the winter I have a couple more questions... She has a basic wood nesting box, do I need to insulate it for the winter? She is alone so no friend to cuddle with for warmth. I built her an outdoor enclosure (see picture) can she be let out to roam and explore leaving the door open so she can go back home whenever she wants? Just trying to get this right so any info you have to share would be appreciated! Also if I left out any important information please let me know! Thank you in advance for all your help.
