Just an update on this girl. I don't think she was in blue for those pictures, but I did find her in blue on Sept. 9 and she shed on Sept. 18. Here are some more pictures taken Sept. 20. I don't think she looks appreciably different, but some of these pictures might be from better angles. I wasn't familiar with caramel at all, so that wasn't one of the options that popped in my head when I first saw her, but I can see that as a possibility now after looking at a few caramel pictures. Still a mystery! The eye is dark grey (which didn't seem to jive with either ghost or caramel?) and the shed had melanin (not that that tells us anything).
For anyone saying a locality corn, I don't know if it makes any difference that I'm in Canada?
I haven't had a chance to get outside for pics with her, but some of these are without a flash. The room they were taken in has a florescent light.
This one shows the salmony-pink colour she has on her sides.
