New Mice

What does the satin mean? I absolutely love these mice. They are regular pet store mice. I actually got them from a store that specializes in reptiles and these were meant as feeders. I'm hoping I can start handling them soon (don't want to stress them out too much) so they become more comfortable with being handled. The buck, once I got him into my hand was very content to sit in my hand and check out my fingers, even cleaned himself a bit. He's very cute. And I love the two does. The other female looks like her hair is not as long and its smoother. So would she be a blue? She's the exact same color.

Most of the time that store carries albinos, black marked, some agouti marked (on rare occasion) and black selfs. Mice like this are a nice find there. So without knowing their background, what might I produce with a pairing like this?

I am absolutely in love with this male. The girls are pretty too though. I can't wait to see babies from these guys.

What will they produce? I know we can't know for sure since we don't know what their parentage is, but anyone fancy a guess?

And what would the genetics of the black satins be? Would they carry the gene for blue? Is satin recessive? Sorry, I should probably be asking these questions in the Genetics section.

I know they all come from the same source. Now the two does are half the size of the buck, so I'm pretty sure the does are not on a sibling level with the male, but if the supplier has long haired satins in his colony, do you think there might be a chance of them being too related to breed?

I don't know their exact ages, but I'd estimate them to be around 8 weeks or so, so they have another month to go before I put the boy in with them. I had him in there with them at first but then I separated them. The boy is in his own 10g. I finally got a picture of the other doe. I'll upload it in a few minutes. The flash kept washing out her color so I'll post a picture with flash and one without.

They are still around 19-20g right now. They were kept in a tub with other mice so they may have been in with males for a while. When I had the male in with them for a few days he showed no interest in breeding with them. I think they were too busy getting used to their new surroundings. I will provide them with extra food just in case though.

Well I've had them for about a week now, so I suppose we will see in about 2 weeks. Is there anything specific I could be giving them just in case they are pregnant? Any fresh foods?
