They all seem big to me as well? She is adorable. She looks like a shaded/sable chinchilla to me, which is not really a thing. The thing is the chinchilla and sable gene should be the same gene so that can't really happen. The best guess I have is that she is an agouti sable, and I am basing this info on this page, which has a agouti sable mini lop near the bottom of the page https://www.barrowbunnies.com/the-sable-gene.html
