Bedding and Feed?

So now that I've decided on a rack for breeding rats, what do you all suggest for bedding and feed for them?

Aspen And mazuri

Food will depend on what you have available locally Mazuri 6F,Kent food.

Bedding I recommend pine pellets (very absorbent which help control the smell) and pine shaving for females with babies under 2 weeks of age (nesting material)

Awesome, I was thinking about mazuri and wood shavings, just wanted some other opinions.

We use pine pellets with a thin layer of kiln dried pine over it for our breeders and growouts and then just the pine shavings for maturnity tubs.
Like Deborah said food can/will vary depending on where you are located.
We use Star Milling and really like it, plus it is quite a bit cheaper for us compared to Mazuri.

So do you that breed suggest that I just get a large number of young males and females and start all at once or start with a 1.4 and then a few weeks later buy 0.4 to populate the second tub and a few weeks later again to do the last tub?
