When I had WAY more snakes & bred some too, I bred my own rodents & sold the surplus, which was actually more lucrative than the snakes...though I was
never seriously "commercial" about the snakes I bred (& I had many rescues, native & otherwise with no breeding intentions at all, just a love for the snakes).

I've never cared for being dependent upon other sources for the right size prey items needed, especially since many snakes really need to start off right on live,
then switch to f/t when feasible. As mentioned in above post, many commercial sources of rodents (especially the 'cheapest' ones) cannot be relied upon to
feed their rodents quality food...and truly it comes down to "garbage in = garbage out". Or as one ad for rodent chow used to say: "feed your rodents the
best...just don't tell them why".

Now I keep way fewer snakes with no breeding, & for convenience (& never running out*) I still breed my own feeders. *Keep in mind that when snakes are
eating the most in summer (due to warm temperatures & breeding), that's when some rodents slow down production (depending on temps. they're kept at) &
therefore some big suppliers can run short. So if you do out-source your feeders, make sure you stock up in advance of summer shortages.
