Oyster shell calcium or home made 'cuttle fish' calcium....opinions

[henward]

its way cheaper to buy the cuttle fish and grind it up.
in case you dont kow what im sayin, the cuttle fish is the stuff that you put on your parrot cage and they chew it and scrape it as they need it.

now
i have repcal calcium with no d3 and phosphorus. it says its pure oyster shell calcium

now, the cost is literally a fraction if i grind up my own cuttle fish. Its easy to do.

is it the same?
has anyone done this? using parrot cuttle fish and grinding it up to a fine powder?

There was a thread about this awhile back. I don't think anything was 100% concluded but I think there is a really interesting website linked in the thread with the "nutritional" analysis of cuttlebone:

I buy human grade calcium with vitamin D at the store and blend it in my blender. I have used this for 10 years and have produced over 300 hatchlings and all of my geckos have always been top notch..
