I'm glad you're coming to terms with the reality of this. We all know this is not the "fun" part of our hobby. The reality is our pets eat other animals. And, it's safer for our pets to eat something that can't fight back.
Really only two choices, pay someont to do the dirty work (buy F/T) or do the dirty work ourselves.
I myself have put down thousands of rodents and while it gets easier over time, it's still not pleasant!!
I know you already know thi but it's important to NOT let yourself get back nto this situation once you dig yourself out.
Unless a rodent breeder has an outlet for surplus animals, you NEED to control production somehow. If tub breeding then by how many females actively being bred. Another method I have used for years is cycle breeding. Putting non pregnant females into the males tub when I want to start litters and pulling them out just before giving birth. This way you know the max number of litters you are going to have in any given week and can adjust up and down as your needs and supply change.
