Chantecler Chickens

Wondering if anyone out there has Chantecler chickens, and if so, what do you think of them? I live in a cold climate (new england) and have been trying to add only the most cold resistant chickens to my flock. I heard these are the gold standard for cold tolerance so I’m interested. My birds have good solid shelter and it’s not like I’m in an alpine climate or anything, but in winter temps dip into the low 20’s regularly. Does anyone have pictures of theirs they could share? And how are they as egg layers? What is their temperament like? Thanks in advance!
