New Pets, Mice

[Synirr]

It's nearly impossible to sex mice before they reach sexual maturity, I wouldn't count my chickens before they hatch

From what I've read for you, 3.5 weeks is a bit early. They're gorgeous!

I'm really not sure about mice, but when I bred hamsters, I could sex them 100% from a couple of days old.

I can sex rats from a day or so old, not sure if it's as easy for mice, but I would imagine it's not difficult, especially when they get to a couple of weeks old.

I took pics of babys and I know now how to sex them. About sexing here.

This is a boy:

And this one is a girl:

Those were easy. But what do you think this is? A boy?

And is Beroccas baby boy or a girl? Boy? Two days old in this pic.

My information of separating etc. is from Finnish Pet and Show Mouses Association so I must trust that.

I would say the 3rd one down is almost certainly a girl too. The last one I'm 90% certain that it's a girl as well.

I hope you are right Bloo.

For a comparison two more certain girls:

Actually you know what - I'm almost certain that last one is actually a boy

[thapsus]

I think so too. Unfortunately.

Yep, looks male, but you'll know for sure in a week or two.

There's no need to worry, I'm sure they'll find fantastic homes and it was to be expected that some would be male
