Breed guesses?

[mnyablonski2796]

I have looked at the thread trying to figure out what breed these rabbits are. I know one is a dutch but I am unsure of the others. The one of the trio are all siblings if that helps at all. They are also all full grown and 2+ years old.

They are probably mutts. It's generally the case for rabbits. I'd say the one next to the dutch looks like a giant chinchilla, probably not pure.
Here's one: http://www.ffc.asso.fr/ffc/les-races/races-moyennes/28-grand-chinchilla

For the 3 others, considering there is a REW with two rabbits who look like they've got English spots in their ancestors, mutts for sure.
