Anyone recognise this book description?

A children's book, not recent. A young girl finds a old jewellery box or chest at an antiques store and which contains various items eg a bird's egg. they turn out to be magical.
Any ideas?

Thank you but I don't think that's it.
I am thinking it is a children's book and not so recent.
Thanks though!

A Pack of Lies by Geraldine McCaughrean? en.m.wikipedia.org/wiki/A_Pack_of_Lies

What the witch left?

Is it an Edith Nesbitt book? 5 Children and It maybe? Or there's another about a phoenix?

It’s not The Phoenix And The Carpet, because the egg is rolled up in a carpet, not in a box.

@redtypistbluetypist any of these suggestions any good?

Thank you to people who have given suggestions!
I've read Five Children and It so don't think it's that one. However What the Witch Left and A Pack of Lies both sound promising and I am going to get my hands on both of those titles. Thanks again!
