I'd just ask if and where the blood /
bone meal in there is from cause bone meal is a common component to it. Its great to feed worms a sand or digestive aid but bone meal is something I personally avoid in the worms diet. All meals infact I prefer to send to the thermophilic natural compost where heats can rise and not threaten exploding worm populations, as babies are more sensitive to conditions!
and also clarify its its
chick starter mash or laying mash. Calcium is usually the main difference here, and that said, its always good to know the source of calcium, I personally would opt for cleaner greener calcium like kale or spinach fed to the worms but to each their own. Whether medical or not I would go clean as possible.
My favourite thing to spark insane* worm breeding is tossing in
halved avocados, its also high in mains and enzymes and supports a lot of life with all the vitamins and minerals. I feed them six shells a week per bin and they breed like crayyyyzy in them all
The only other thing to perhaps look out for is are you gonna get pellets, crumble or
true mash aka the cornmeal consistency. I'd say the best is the latter (cornmeal) for worms but for chickens I think pellets is easier on them.
