Great Post!
Very well written, described, illustrated and thought out.
I have a note or two to add about diet. When I was breeding rats a while ago, I was told from a couple of sources to avoid citrus fruits for mice and rats. It contains chemicals in the fruit which can render them sterile and cause reproductive tumors. That same chemical is also found in Kaytee brand rodent food, go figure. If only I could remember the hazardous ingredient.
I had switched my rats from Kaytee (cheapest) to another brand without the chemical and within a few months noticed my breeding rate increase and the health of the rodents dramatically increase as well.
Could be pure coincidence I'm sure. I wish I could find more documentation of that. I originally saw it discussed on the Kingsnake.com Rat Forum.
And I must say I'm jealous as hell at the wide variety of colors in your mice. I have plain jane white lab mice, booooring. I purchased them from a mouse breeder who got his original stock from a lab. So they're good quality and produce like the dickens. Just now starting my third round of babies, a litter born each week. I held back a couple female offspring to increase my breeding colony to 1:6. Need more pinkies. =P
My setup is a 20 gallon reptile aquarium with mesh lid. I have a hand towel spread over 3/4 of the lid to keep the drafts out. They have a wheel and one paper towel tube. Aspen bedding is used and I have a 50lb bag of custom formulated lab blocks from the breeder. They do great on the stuff. If you want nutritional info lemme know and I'll get it from the tag on the bag. =)
Thanks again for the info, helps immensely.
