Two Holland color-development paths

Illinois Extension distinguishes the foundations of White and Barred Hollands. Its history connects White Hollands with imported Dutch birds and several American utility breeds; the barred population followed another selection program involving Leghorns, Plymouth Rocks and Australorps. The shared goal was a useful meat-and-egg bird with white eggs. The name therefore refers to an American breeding project with Dutch connections, rather than every chicken raised in the Netherlands.
