The standard was written in 1922 and some of the wording is not very clear. This page offers some help and advice on interpreting the standard.
A great deal of advice can be found in the articles in the Feathered World Yearbook section of this website.
You can find more help by joining the Marsh Daisy Breeders Group Forum (this is a moderated forum so you will need to register). On this forum you can ask (or answer) questions and submit photos.
1. The breed standard says legs should be willow green. What is "willow green"?
2. What is the Marsh Daisy "type"?
It is often said that "type" is the most important characteristic to achieve. Perhaps type is easiest to understand by looking at the photos section of this site, which includes both modern day photos and photos from the Feathered World Yearbook.
