Other places to get calcium and minerals from for your ferrets is
cuttlefish bone, egg shells, crushed oyster shells and of course small
animal bones like chicken, Cornish game hen, rodents.

Cuttlefish and crushed oyster shell can be found at pet bird supply
stores. Egg shells - well from wherever you get your eggs. Keep in
mind that modern eggs are bleached so it's wiser to get (and tastier)
organic eggs. It would likely take an awful lot of modern egg shell to
adversely affect the ferret, but with other choices out there, why risk
it? Toast the shells to help them release their minerals ( a nifty tip
from Bob Church). I use a coffee grinder to turn all these to powder
for mixing into their soup, dredging their gizzards, or dusting raw
meats.

Do NOT feed dry cooked bones! They don't crush when chewed, they
splinter. You can boil & simmer or slow cook the snot out of them until
they can be crumbled between your finger tips. Then mix into their
dinner.

Reptile suppliers sell all manner of calcium supplements but avoid the
ones with sugars, colorants, titanium dioxide etc.

Crickets are reported to be fairly high in calcium and can be found
live or freeze dried.

Of course mice and rodents come prepackaged with the ideal mix of
minerals and nutrients and also can be fed live or prekilled.

Heavy cream and soft cheeses make tasty healthy calcium filled treats.

Cheers,
