Aww I'm sorry for your loss, I know it was a while ago but its obviously still upsetting you. Many things can take a bunnies life unexpectedly. there is no reason to blame yourself
I'm no expert. Mine have always been inside however I know that it sounds like they have a cosy & fun new home to look forward to. Cardboard boxes stuffed with straw provide lots of warm & extra snuggle opportunities. I don't know how size impacts but I'd have thought the higher activity of smaller buns would go in their favour.
