I have 2 from a couple years ago hanging on the coop. I put the square one up the other day, but I want to put the “Waddle On In” one on the duck gate, so I have to take another one off first. And I used screws, so haven’t swapped them yet. They are actually decent little metal (painted alum?) signs. One has faded some, but I think they are cute. Especially for free.
Here’s one of the older ones

Nice! Who cares if the poultry can read the signs, I would enjoy them...they'd make me smile seeing them every day.
