And for those that want a black bird to outcross with lavender the wider feather is very important to improve feather quality of future generations of lavenders.
My friend, Ken Aho, is a top breeder of partridge Plymouth Rocks and he claims feather width is very important to get the proper penciling pattern on feathers. So that is something for those working on partridge Ameraucanas to consider and maybe other varieties with different colors within a feather.
