Shire and Percheron are separate breeds:
* Shire horses are a draft breed originating in England, known for their size, strength, and calm temperament.
* Percheron horses are another draft breed, originating in France. They are also large and strong, but often have a more refined build than Shires.
Grey horses are simply horses with a coat color that turns white as they age. This color can appear in many different breeds, including Shires and Percherons.
It's important to note:
* A horse described as "Windsor Grey" may simply be a Shire or Percheron with a grey coat, but it doesn't indicate a specific breed line.
* "Windsor Grey" is not a recognized breed name, and there is no official registry or lineage associated with it.
If you are interested in a particular horse described as "Windsor Grey," it's best to ask the owner about its specific lineage and breed.
