Is sharing a cuttlebone ok?

[sparrowsong98]

Hi guys. Last week when I bought Willow, I somehow completely forgot the cuttlebone. Addy, my other finch, has a cuttlebone though. I was wondering if I could scrape a bit of Addy's cuttlebone off and give it to Willow, or would that break quarantine rules? I am sure that Addy is healthy, and the cuttlebone looks clean. I would go out and buy her one, but Walmart doesn't sell cuttlebones, and I am not going to be able to get to the store for a week or two. Would this be ok as a temporary solution?

It sounds ok to me.

Why not just crush up an egg shell and put some into the food dish?
They really don't need a lot of extra calcium if they are not breeding.
