I'm not that good at sexing at this stage, and from pics it's quite hard.

1, 5 and 10 look like females. with the rest males.

wait for others to see. I'm new to mice, but have had rats for years. usually you can feel the testes on the boys by gently rolling your thumb over the area. Wait another week if you can and all should become clear.

1 - Female
2 - Male
3 - Unsure... i'd say male, but the bump doesn't seem to stick out enough, wait for nipples or not.
4 - Male
5 - Female
6 - Male
7 - Male
8 - Male
9 - Male
10 - Female, I think, but again, wait for nipples
11 - Male

I agree with willowdragon; with some babies sex is quite clear, with others you just have to waity a little longer.

with my current litter of rats there was one that looked male, turned out to have nipples!

 

[nanette37]

ahhhhh it would be just my luck to have that many males.. haha thanks! i'll look for nipples today. ahhhh if only you were wrong and they were all female.. haha but i know you're right :lol:

When looking for nipples, don't be afraid to hold the baby up to a light and turn it so that the light catches the nipples just right. With practice, this becomes easy. I think I invented this method. lol

Ten is a lot of babies!

 

[nanette37]

there are actually 11! . im going to go look at them right now and hope i see nipples on some of those boys!

 

[Jack Garcia]

Just look for little tiny "dimples" in the skin. That's what they look like at this stage and the light helps you to see them.

Or, wait a couple days.

 

[nanette37]

alright i culled 4 unhealthy babies so here are the 7 ones left

im pretty sure i saw nipples on these:

and on these ones i definitely saw no nipples:

The nipples are very easy to see just a day or two after the fur comes in on the belly at about a week or so.

 

[nanette37]

well they are 10 days old now and im still having problems seeing them . but by tomorrow i should be sure

Just takes practice, with marked or mixed colours its easy to practice (because you can tell one from another) so as soon as colour comes through write down what you think they are and then when they fur is through enough to see nipples see if you were right or not. Give it a few more litters and you will be able to have a good idea when only a few days of age.

Also congrats on some lovely colours.

thanks for the advice . i'll have to try that with my younger litter right now. i can really tell them apart but i can always mark them
