Ok, I know there are alot of rat breeders out there. I started breeding my own rats to offset the cost of buying them, and to have them on hand to feed hatchlings. The breeders I know don't care what the breeds are as long as they produce. I know I have a lot of mixed breeds. What do I hold back to breed out of what you see in the pics, and what kind are they? I have more pregos ready to drop anytime, so I will post more pics later.
Thanks for any help!
