You can also look at options if you do get a bit overrun with extra feeders (other than the obvious of trying to control the breedings of course). Some private pet stores will take good quality live rodents in exchange for store credit, also look into any local herp or raptor rescues that might like the occasional prey donation, check and see if you have a local herp club where you might be able to sell off spares, post at BPNet if you have extras in case another member lives close and would like to purchase them - just a few ideas.
