I did a Google search to see if there was a patron saint for chickens, and discovered that St. Brigid of Ireland is the woman for the job.
I found this online - it's not my stuff but I'm buying one to hang outside my coop. They do tiles and wooden plaques. Just thought I'd pass it along in case anyone else has some latent Catholic in them like I do...

My little flock includes a white Silkie and a Belgian Mille Fleur d'Uccle who is currently raising three chicks; a Barred Rock, an Ameraucana and a Buff Orpington.
