8:52 - ? shifting on eggs (?). the hen began making bobbing motions with her head, as if reaching down to pick at something on the ground, while maintaining her body horizontal, sort of hunched. In the course of 2 min.
she rolled about 14 times, rotating her body around twice through 360°. At one point, she appeared to
lie on her side - "listing". Could also see her back feathers
rise - from the heat. Only once did she sit "straight"
up to look out. Seems like a lot of activity to me.
Possibly even some "dry tumbling" going on - or if she
were about to take a bath in cold water.
8:58 - ? her settled down or completely again. I think her back
is towards me. The weather was cold, clear this morning
Light lost on grass in shade. Heat waves now rising
off ground in sun - the pothole must get quite warm!
9:03 - Nearly entire upper half of pothole in shade:

9:06 - ? shifted again. 9:24 - ? sitting up, looking out of
pothole, then shifting, picking, shifting, rotating, shuffling
in scrape. Rotated at least one, now facing
out of pothole. Lots of head motion to eggs. She might
be panting from heat. 9:30 settled back on eggs.
9:57 - ? still in pothole, on scrape. It looks like she is now
partially in shade, pothole is over 1/3 shaded on the back
