Weird looking genitals and pregnant ladies

First some pics of 2 mice I found out to be pregnant yesterday. The pied lady more obvious than the brown one, but both very apparent, even for a novice (me)... :crazy02:

Last pic in the reply is from a lady I had sitting with a male for weeks. That male put the other 2 with babies so he's fertile, but this lady didn't get pregnant... I put her in with him 'cause her genitals looked a little swollen (not reddish) so I thought maybe it was a sign of being in heat... Since she didn't show any sign of being pregnant after 5-6 weeks I decided to set the male with some other females. Her genitals still look the same today(after 3 weeks of being with only female and 1 week with a teenage male added); swollen, not reddish and somewhat 'opened'. There seems to be something sticking out in the lower part, it's pale pink and not hanging loose or so so I don't expect it to be intestines or internal tissue... When touched it feels solid, not wet and not slimy. It seems to stick out more lately. Her condition seems a little off; lost some weight I think though I'm not sure really. Further she has shown to be allergic to aspen, so she's a little problem child... I'm thinking of feeding her off but maybe some people here know what it could be and how to cure it without vet bills. Cause she's a breeder animal and not a pet after all... Or shouldn't I feed her to the snakes because of this?

The weird genitals (never thought I would ever be concerned about mice genitals )

2 pics of the dad of the unborn mice; 1 taken today (mouse on foreground in the wheel) and one from when he was a teenager.

Can anybody tell me if a grey piebold with a 3-colored piebald produce piebalds and if so what color(s)?

Tnx!

Nobody? I don't know what to do...

Hard to tell from the pic but if she is not fertile, and the genitals look swollen and red, she could have a uternine infection. There could also be some discharge. I personally would not feed her to a snake, especially if her health is visibly declining like you say.

I wouldnt risk feeding it to a snake... Mabe put it out of its misery another way.

Well, the genitals didn't look red, but a little swollen..... 'cause it didn't seem to be contageous (parasite) and snakes have very strong digestive juices I did feed her to my snake and it gave no problems, as expected. She was not that ill, only a little thin and maybe a little slower/less alert but I was not even sure about that. Most important reason was that she didn't get pregnant....
