WOW!! She is looking huge!! I think you are going to have to more or less forget waiting for her udder to show you any 'final' stages and put her down to one of those girls who will bag up properly at foaling time. She looks as though she is going to produce very soon to me - I would be keeping an eye out for any changes in the colour inside her vulva to give you your 'last minute' signs.
I will post pics from this evening in a little while. My computer is in the living room and my 6 year old has his older friends over...they might start to wonder if I pull up pony porn on the computer, lmao. She is looking about the same, but I DID checker her vulva color. It was pink, but got a good bit darker deeper in. Very different than the normal pink all the way through. She isn't really showing any behavioral signs though. Eating her hay right now. MAYBE a little less active? Seemed to stand around a lot, rather than picking through the green stuff in the yard today.
