Actually orcs went to find refuge in the Ered Nimrais in about the half of the Third Age after they were defeated by Gondor and Eorl the Young when he came down from the North riding Frealaf and saved the Gondorian forces from being utterly destroyed. You can assume that some made it and set up homes deep in the Mountains.
