Hi,
Hope you don't think this is too weird a question but I am wondering about male genital development in IPS. Why? I will tell you.

My girl squirrel, Durga, gave birth to 3 babies. They are over a month old, now, running around. I have decided not to touch them and let them be completely wild. But, since they are living in a house we made for them up on the wall in the porch room, I get to see them grow and run around.And take tons of pictures. I noticed something, in one of the pictures, under one of the squirrel babies, "Little Gray", as I call him, because he is all grey with 3 blackish stripes and a little tan on the part close to his legs, quite a different color than his siblings and most IPS. I noticed a ball sac, quite a big one. In fact. My 2 boys didn't get that big of a sac until the 3rd month or so and now, in their 9th month, it has completely matured. This little guy already has the sac of like a 3 month old, although proportionate to his size.
I am wondering if something is wrong here? My boys had tiny little testicals, looked like tiny flaps of skin, until around 3 months old when they finally filled out into 1 piece. But this little baby already has the torpedo shaped sac. Is this normal?

Since the other two babies don't have this, but little button wee-wees, I am not sure what they are either, m or f, because all my babies started the same. They had nothing but a button wee-wee and fur, as two of these do.

I have searched the internet and cannot find any pictures nor answers. I am hoping someone might know something. I am sure Little Gray is fine. But, it is me who is astonished and wondering!!

Of course, this all started as I was wondering what my female squirrel had, in way of boys and girls.

Thank you…
