I have no idea about the origins of these leghorns other than they were hatched in a classroom project. Don't know if the eggs were ordered from a hatchery or they came from someone local. I suppose I could probably find out. If they came from a hatchery, I assume there is a lesser chance they are related? Regardless, definitely can't keep them all. But glad I can have a few to pick from. Unless we end up with a Wyandotte or Brahma rooster from the last 10 chicks we purchased, would like to keep 2 of the leghorn cockerels.
