Thanks Sally, Sean and Liz.

You don't need to give gravel to finches, like you do for budgies, but they like mineral mixes. Oystershell is excellent for calcium, if you can't find it at a pet supply place, look into stores that sell feed for poultry.
Below is the type of oystershell what we get it here in my place and also here we don't get/find any ready minerals products, so we need to make one on our own in the home for our birds.

Been working on getting the store ready for the Grand opening and then actually opening the new location.
Looks like the steps you mentioned will work for sterilizing egg shell just fine. It also look like you got a couple of other tips that as well.
You moight consider telling the other forum to come over to the finch side and see what we are cooking.

Nice to hear about your shop grand opening and hope you are still enjoying the wonderful and memorable events of the occasion.
My personal understanding from Budgie breeders is that, since the chicken egg shell membrane is of organic in nature, so we can't preserve the egg shells with membrane for long time. If we don't want/plan to preserve it for long time then we can serve the egg shells with membrane.
But here I learnt from Sally, that we can even preserve the eggshells prepared with membrane too for long time.
Is there any time limit after which we shouldn't use these preserved egg shells with membrane to our birds which will harm them.
