I think she's probably doing just fine. Sounds like she has some good edema in front of her udder, and that will begin to move back and fill her udder. So, it sounds like she's getting closer every day. If there was something wrong, she would be showing you signs of distress, I'm sure. So, since she's doing good, and just rubbing that baby into place, I'm going to say, we'll see the baby when she's ready. And we KNOW she must have that little one eventually!!
No worries, I'll give Deb a call (she's still waiting on 2 foals who also are not being very cooperative) and let her know the progress. But really, I'm sure this little momma would be showing some severe signs if something was wrong. Take a deep breath, we're all here for you and this little long ears!
