royal eggs , talking birds

im looking for an old animated children (non-disney) movie . i dont remember that much of it. all i remember is , there was a little girl with brown hair and blue eyes , she recieves royal/fancy eggs with talking birds inside of them. i remember that ‘swan lake’ was one of the main soundtracks . and the places in the movie are cold and snowy (look like russia) does anybody knows what movie is this?

Got something to say?
