i looked up the term that your grandpa used and no search was available which means it was some word he made up. also the black, barred,brown,blue,pile,lavender leghorn originate in holland and in the uk you have to be a member of that club, if you do a search you will find it. bear in mind the prices maybe so high that they wont post the prices on the site. i dont know if you join what the price is. but i did the search and that is what i have found. if you intend on buying them be prepared to pay a hefty price for them. they were accepted in the APA, but the way they get the color combos is a lot of mixed breeding in order to get the spacific color. i figured you should know
