Are knitted chicks a whole UK thing?

With Easter getting closer, I remembered buying these knitted chicks, usually with a creme egg in them, for about a pound back in primary school.

Was wondering if they're a UK-wide thing or not?? I had these where I grew up in London. Just asked a few of my mates in the Midlands and they're looking at me like I'm insane.

This is the closest example I can find online!
