I have the original White Chantecler. They are large Fowl, the 1st original breed from Canada. Bred by a Trappist monk in Oka Quebec over a ~10 year period up until 1917, admitted to the APA in 1921. Bred to thrive in our winters.
The Buff Chantecler came later in the 80s, not yet(?) admitted.
This is my boy with a chicken friend for her initial inspection. Sir Wilfred will replace a Black Copper Maran mix that attacked her at least a couple of times; after 10 minutes Lindsay said "such a good boy" as you can see the breed is known for friendly calm demeanor.
