Update: We have eyes!
Everybody's eyelids are separating. I'm feeding them 0.5 - 0.7mls of puppy formula every 3-5 hours. One has been notably harder to get to eat and was having some skin tenting, but it was really eager this last feeding so hopefully will do better. They're all active...so cute watching them try to groom themselves without falling over. Also, now that they can see a little they've been much more commited to hiding themselves in the bedding when I open the lid.
Today I also offered bread sopped in formula in a little dish. We used this with great success with some wild baby bunnies years ago. I have not seen anybody eat it yet though...
