I've seen Cordie jump in and move the covering fur off and 'check them'. I haven't seen her feed them, but I was under the impression that you wouldn't see that most of the time? I have read that she might not feed them anyway in the first 24 hours, and that's okay, is that right?
I will try and keep an eye on her anyway, though even if she's in there she tends to jump out quickly and give me a dirty look if I go in the room.
And I will check the babies again this afternoon to see if they look any fatter.
Raspberry.. I think is glad to have a break from the hormonal Cordie, actually! She's been enjoying her own space and the ability to DBF without getting her bum fur tugged out. They still have contact through the NIC grids anyway so I don't think they are missing each other too much at the moment anyway.
Cordie is doing okay. I don't know, she seems on edge a bit but I guess that's to be expected. She's spending a lot of time loafing on top of the cardboard box I put in - I cut the side off a cardboard box and put the nestbox in it, since she seemed very nervous having the nest 'in the open'. It seems to have calmed her down some.
