Hi, guys!!! I am new to owning a pet mice and it was given to me by a friend. I have no idea how to sex a mice and need help doing so that I can know to get another female or male. Sorry if the pictures are a little blurry he/she did not want to stop moving even for a second lol, and don't worry I'm not squeezing him/her I just made a tunnel shape with my hand so that it could crawl around comfortably.
 



Edit 1: Thank you so much guys for the warm welcome and trying to help me! And to answer scaredymouse's questions my friend is a small scale breeder and usually breeds mice as food for his reptiles and from what I learned from him our little guy/girl is 3-4 weeks old.
Here are some more pictures I tried to take of its little bottom.



And the little guy/girl is definitely cute loves crawling all over my hands and everything else!!!

Looks like a girl to me, but you might want to wait for more of an expert to comment. Just letting you know, males must live alone but females must live in groups—preferably groups of 3 or more, because it works a lot better to make a well-functioning hierarchy.

Welcome to the forum  

Based on the pictures, it looks like it *could be very young boy to me.  It's so hard to tell the sex from these pics.  I don't see a vaginal opening or testicles. Do you see any nipples on the underside?  Nipples aren't visible on male mice.  If you do have a boy on your hands, he needs to live alone.  Male mice fight violently when housed together.  Let's see what everyone else has to say.  

Did your friend have a mouse that had babies?  How old is this little one?  I can tell from his butt that he's cute, lol.

I agree with scaredy, I think it looks like a young boy but I'm not 100%.

I have no clue what gender your mouse is but I just wanted to say

Welcome, leekthy! I won't guess since these pictures are kinda hard to see on my phone, but have you seen the sexing page? It's got great pictures you can use to compare.

Kinda looks like a girl to me, but then again, everyone seems to be disagreeing. Can you get clearer photos? Try putting them in a clear container like a glass jar and taking pics from the bottom.

With the new pictures, I kinda think it looks like a girl too. Whatever it is, it's super cute!

I vote girl.

Definitely hard to tell at this point. I would hold off getting any more mice until we're sure if you've got a boy or a girl. Were you able to spot any nipples on the the underside? If possible, try to put the little one in a glass bowl and take a picture from underneath.

one thing is for sure, you've got a cute little fuzzy on your hands
