My I would not breed for only one BP. Y

You will have anywhere between 6 to 12 rats per litter and they will grow fast and you will only need one rat a week.

While F/T is a great way to make sure your don't end up overstock with large rats that cannot be fed to your BP, it requires that your BP eats F/T to start with. Also keep in mind frozen rodents do not last forever in your freezer either.

One more thing taking GOOD care of your colony is not cheap just like with any other animals they must be provided with good care and quality food, and even than things can go wrong.

Finally you need to think about the work that is involve with a colony whether they are rats or mice and make sure the it is worth it, thinking you only have one BP.

I breed my own rodents (mice and rats) and I started when I reached 10 BP
