Workers at the Lafarge Costessey Readymix site in Norwich are finding cute coneys at every turn.
But these are not the flop-eared, furry hoppers of field and forest. These particular cottontails are made of stronger stuff – concrete to be exact.
And, they are causing quite a stir both among the site staff and local schoolchildren.
Barry Hewitt, Lafarge Aggregates & Concrete UK sector supervisor, said: "It all started as a bit of a joke. When we produce a batch of our special free-flowing flooring – Agilia Gyvlon Screed A – we always do a sample first for testing.
"One of our drivers brought in a rabbit jelly mould so he could use the leftover concrete to make a bunny for his daughter. It was a silly idea but it has really taken off. We've got bunnies all over the place now."
To help thin the population down, Mr Hewitt suggested donating a few of the figures to a local school. Plant supervisor, Ricky Mapes whose children, Caitlin, 10 and Aden, eight, had spruced up some of the rabbits with a lick of paint, came up trumps with an arrangement to hand over 27 of the rabbits to their school, Henry Preston Primary.
