How we check the facts

Every number on this site can be traced to a published source. Here is how we work.

Where numbers come from

When sources disagree

We show the range, name each source, and say so on the page. We never average two sources into a number neither of them gave.

Planners

The drawings

Breed portraits are drawn from simple shapes to show each breed's usual colouring, comb and feathering. They are friendly illustrations, not show standards.

Corrections

Spotted something that looks off? Write to hello@yolkday.com or use the contact form with the page and the number. We fix confirmed mistakes and update the page's review date.
