How interesting, thanks for the update.
2000 mice, wow, you will have your hands full!
Hope to see pics when you can sort the camera :)

Pitbull- Siamese Splashed
Blavenous- Regular Black
Wyvern- Beige Splashed
Holmes: Burmese Splashed

Primary Lines:
Seal Point Siamese Normal and Splashed
a^e/a^e ch/ch Spl/*
a^e/a^e ch/ch spl/spl - Primary Goal
Extreme Black
a^e/a^e C/* - Primary Goal
Roan/Merle
a^e/a^e C/* ro/ro
a^e/a^e ch/ch ro/ro - Primary Goal

Secondary Lines:
Variations of Brindle, including:
A^vy/a^e c^ch/c^ch Spl/spl s/s - Primary Goal

Recent images depicting a few of my does, sorry I didn't have time to take photos of all the does or any of the bucks. Enjoy! :mrgreen:

Update November 11, 2018:

Mice are doing well. However, slight increase in deleterious gene expression due to compounding inbreeding coefficient.
2 randomly deceased offspring
1 doe with mammary tumor growth at 1.5 years of age
5 cases of respiratory illness due to immune deficiency
3 cases of decreased size

I have officially isolated my mousery, in which I will no longer be accepting new outcrosses any longer. I felt that a lot of the foreign mice displayed health/vitality defects and non-preferred recessive genes related to morphology. The only trait I feel that I have improved from outcrossing was slight increase in size. I have decided to pursue the creation of a book about mouse husbandry, specifically regarding developing morphology and line management to minimize inbreeding depression. I never found an intensive interest or indulged in coat color. I will also be abandoning my pursuit of Seal Point Siamese, as I do not promote or like the red eye manifestation due to visual impairment within effected specimens. Thus, directing my sole focus on Extreme Black and Siamese Roan- black eyed mice.

Current mouse population is greatly decreased, however inbreeding depression should not be an issue because these individuals originate from over 1000 mice. Thus realistic population is minimal, but genetic variance is likely sufficient among the selected individuals.
6 Extreme Black does
4 Black does
1 Black buck

2 Burmese piebald does
1 Brindle buck
1 Burmese Tri-color buck

3 PEW does
1 BEW doe
7 Siamese Splashed does

5 Roan does
3 Burmese doe
1 Burmese buck
1 Colorpoint Beige buck

Here are images of my latest favorite buck, named Security, whom is a Colorpoint Beige. He has a slight tear in his left ear as an injury from fighting with his brother. Security has since acquired his personal tank. He just turned 7 weeks today. Happy Birthday Security! :P

I really enjoyed reading about your project! I think your Siamese are my personal favorite of the bunch, but they all look great :) Looking forward to seeing how they progress!

Thanks, glad you enjoy the thread. Yeah, Seal Point Siamese was my favorite for a long time too.

Update December 4, 2018:

Within the last two generations, respiratory illness has become apparent within my mouse population. I hypothesize that a few of the outcross individuals from 3 generations ago carried poor immunity on the X chromosome. I predict that the negative immunity genes derive from the X chromosome because the illness primarily affects my bucks. Since I am genetically purging the lines, the frequency of respiratory illness has slightly increased.

Security, my previous selected future stud, has fallen ill to respiratory illness. I am relying on two of my best two burmese splashed does to produce future buck replacements. Fingers-crossed! If replacements are not produced, I will be force to breed to either of my long-term and healthy studs- Blavenous, a standard black buck at 63 grams or Pitbull, a siamese splashed at 69 grams.

Overtime, respiratory illness will be bred out through selective breeding of mice with acceptable immunity- the only long-term solution to such problem.
I currently have two roan litters, produced by Revival and 4 extreme black litters, produced by Blavenous. Hopefully, photographs in my next post.

Hope the health of your mice gets better soon! I've been experiencing something similar with mine.

Thanks! Yeah, I am sure that this issue will be resolved soon. I had this issue before, when I first began my lines. In addition, it is only a few select mice (5%) that are exhibiting respiratory illness. They share similar ancestor from a breeder in Pennsylvania- whom must carried immuno system suppressors for the specific virus strain within my mice.

Also, if you are having respiratory illness develop without the implementation of outcrosses, I would be wary because you may be experiencing increased consolidation of inbreeding depression.
