By looking at whorls we can have a clue about temperament from the time of birth.
There are limitations. One of those is the distortion of the whorl caused by the foal hair coat.
Foal coats do all sorts of interesting things. From colors no where near what the adult color will actually be, to primitive markings. Foal coats will also have curls that wont be present as the horse ages.
Very often the forehead will be wildly curly with concentric circles extending from center. These make the whorls look far more complicated than what they are.
As beautiful and convoluted as the circles are they are still only a byproduct of the baby hair coat and will disappear when the coat sheds and a more adult hair coat grows in.
When looking at foals, don’t let all the pretty extras confuse you. Look closely for the actual whorl. Or wait a year or two for a more easily exact analysis.
