I currently have 2 4 week old mice, im wondering how I can tell which gwnder they are so that I do not accidentally end up with babies. I have watched youtube videos, which makes me think I have girls...but they are very young so at what age would they develop if they are boys?

Here's a guide to sexing mice: https://www.petmousefanciers.com/t45-sexing-mice

At 4 weeks your mice should be at sexual maturity, and, if your mice are males, their testes should have dropped about 2 weeks ago. From what it sounds like I feel like you would know if you had males by now. Smile

Awesome! Yeah i dont see nipples so I was worried, but that's great news. Now i dont have to worry about finding a vet to neuter them. Smile
