The Search Wizard
Overview
This website has a list containing information for all the ponies that currently make up the herd owned by the Chincoteague Volunteer Fire Company in Virginia. Foals that have not gone through the auction in July are not included. The Search Wizard allows you to narrow down that list to a much smaller list based on physical traits like color and facial markings. This is accomplished by ticking checkboxes on and off. In many cases, you can get the list down to 1 or 2.
The number of ponies satisfying the current search criteria is displayed in red at the top left. Each time a filter is selected or unselected that number changes. The View List button takes you to the Results page where you can browse through the list. It's possible to browse the entire herd simply by NOT checking any boxes. If the number found is zero, the View List button will be grayed out. The Current Filters button displays a list of checked filter options. This is particularly helpful for finding accidently checked boxes, especially on your phone where only a few choices are visible at a time. The Clear Filters button unchecks all the boxes.
The wizard has 7 categories of filters to choose from: sex, color, face markings, leg markings, color pattern, brand, and blue eyes. Almost all the categories have a list of choices associated with them. The Blue Eyes category though is an on/off (yes/no) switch. Because checking all the boxes in a category produces the same results as checking no boxes, the system will uncheck them if you try to check them all.
The options that narrow down the list the quickest are blue eyes, sex: stallion, colors: palomino, buckskin, or black, and brand. There are only a handful of ponies with blue eyes. Certain conditions like cataracts, however, may make the eye appear blue when the true color is brown. Stallions make up about 15% of the herd. Approximately 11% of the herd are black, 13% are buckskin, and 10% are palomino. Specific brands make up no more than about 7% of the herd.
The page has been designed so that all the filters fit on 1 computer screen. The mobile version has all the same elements rearranged to fit the smaller dimensions of the device.

Sex
Sometimes it's obvious that you are looking at a boy horse.
Blue Eyes
A horse may have both eyes blue or 1 blue and 1 brown.
Brand
Most of the herd have brands of their left hind quarters. The brand is normally the year that the horse went through the auction during Pony Penning. Often they are not very readable. If you can make out the 1st digit, it may be worthwhile to select all the brands the start with that number.
