There are no known albino chinchillas. What you have is called a Pink White, and no you should not breed two white chinchillas together.
Before you jump into breeding, I suggest reading the breeding forum and doing some research. There is much more to breeding then throwing two animals in the same cage together. One or both of your chins can be killed, you may need to hand feed babies every 2 hours day and night. YOu may find pieces of baby laying around the cage, may need to assist mom and help her deliever kits.. Lots of research should be done..and you should know atleast the basics of chinchilla genetics.
