I don't see any chicken anywhere? This is the screenshot that shows up: https://cinny.in/assets/preview-light.png

I also tried changing the "light" in the url to "dark" and got https://cinny.in/assets/preview-dark.png

They are referring to the chicken on the home page with the second theme (non-pure white) selected:

busymom0 had it right -- I meant the preview for the silver theme :)
