@Brendon Good to have you back, we need all the help we can get. We are definitely not close to solving this as I don't have a clue about the last 2 locations.
Alright, let's review our chicken pathing. I believe we all agree that the chicken was at the Roc's Nest, near Rupunzel's tower. After that this is what happens.
Map for reference.
•The fox was lost and roamed the roads for the rest of the day and through the night. With dawn came a shift in fortune, and he found the chicken’s scent near the tower. Chicken was surprised, and a frantic chase began, through waterfalls and caves, o’er hills and woods, until reaching the shore.
•Chicken would have to swim to safety. But all she could see was water, she could see no land to rest on. Then she noticed the man on the sands who looked out and revealed where the nearest point of land would be.
•Poor fox, however, exhausted from running all day and night and day again, had little energy for the swim and soon got into trouble and drowned. When chicken reached dry land, she shook the water from her feathers and sighed.
•Where had her tale ended?
So the important highlights.
After leaving the nest she travelled " through waterfalls and caves, o’er hills and woods, until reaching the shore".
NEED 1: We need to know where the reached the shore.
Chicken decides to swim for it, but cannot see a place to land. She finds someone to help.
"Then she noticed the man on the sands who looked out and revealed where the nearest point of land would be"
NEED 2. We need to know who the 'man on the sands' is.
Note that a strict reading of the passage doesn't necessarily indicate whether she met the man on the sands before getting into the water or during her swim. She might have swam for a while before meeting them. (But then the question I ask myself is, if she saw someone on the sands...why didn't she swim to them instead of going wherever he was looking.)
NEED 3 We need to know where the 'man on the sands' was looking.
That should be our answer.
There are a few ways to tackle this.
We can just look for every 'man on the sands' on the map, and follow their gaze to their endpoint and list them. I'm keeping 'man on the sands' in quotes, because it might be a reference, or heck might not even be a man. Maybe we all look alike to chickens. That sounds like the easiest way to tackle this, but I'll be damned if I keep failing to find anything helpful.
We can try to trace every possible path she could have taken from the roc's nest that goes through waterfalls, caves, hills and forests to a shore line, then swim from there til we hit a person. That's more in the spirit of the story, but sounds pretty obscure since we don't have a direction, or distance and her run is called 'frantic' which might not even mean she was running in a straight line.
Maybe there's a clue hidden in the last 3 stanzas we're missing? A hint to a location or something she passed that I haven't seen? More sets of eyes on the exact wording given by the journal instead of my parpahrased mumbo jumbo can't hurt.
