Helloooo.
I breed mice. If you have any questions let me know. I have a LOT of them and a lot of varieties. I'm working with short ear and tricolor and trying to get some satin going. I have a doe ready to drop from a breed back that should have satin babies. I bred her back to her grandfather who is satin. I have a bunch of other colors, and banded and piebald, it's honestly kind of a color mess at my place lol.
Here's one of my bucks I produced here. He's over a tricolor doe right now and he's got a couple of does who should birth this week off of him as well. Saturday for those, if all goes as planned (they look pretty big, but not ping-pong ball like yet, so it's still up in the air on if they took, but I saw him do the deed so..).
I do recommend using a good software to track your mice and breeding and lines. I use Kintrax. The free version works fine for me and I am running a huge mousery here. If I get too big I'll pay the fee which is fairly minimal and it is for life.
I feed kind of a weird mix of feeds. A combination of chicken feed, cat or dog foods, and sweet mix (which is a very fatty mix of grains from the livestock store, high in sugars- don't use a lot). I used to feed harlan tekland and I may go back to that at some point but the mice do very well on the chicken food based diet, oddly enough. I did it because I noticed a really large population of very shiny healthy looking wild mice roaming around the chicken pens and realized, hey, you know, mice eat pretty much the same stuff chickens do. It's kind of experimental so I wouldn't do it if I were you, it's an at your own risk sort of thing but yeah that's what I am doing right now and my mice look really good on it.
