I have a question that might sound kinda stupid but... Do you think there should be a category for cold hardy breeds? I am sure most of you remember that winter vortex with the insane weather a few weeks ago. It got down to -30F/-34C inside my coop for two days, all of my birds got through the weather and did very well. I did not think about it until afterwards but I have some chickens that you would not think could survive that weather. I have a tiny Egyptian Fayoumi pullet in the flock, smaller than my silkie bantam rooster. This is a breed from Egypt and it is very tiny, the hatchery that I got her from (McMurray) says Egyptian Fayoumi are not cold hardy breeds-
So this was kinda surprising, I wonder what weather a bird like a RIR could tolerate, a bird labeled with this cold tolerance-
If -30F is poor cold tolerance....
This is just one bird in one situation so of course I can't judge all of the chicken breeds off of this, that's why I made this thread, I want to know what other breeds members have had survive extreme cold. I am also wondering, how do people decide if a breed should be labeled as cold hardy or not? I mean it must take some extreme temps to kill a chicken.
I also have a few Turken pullets who survived the weather in the coop, they are not full grown and are missing a ton of feathers because they are turkens. They still did just fine. Other breeds I have are leghorns and silkie bantams, they did alright too, even though they have "Poor cold tolerance" according to the hatchery.
(turkens are labeled as cold hardy by the hatchery but these ones are still pretty much chicks)
So I am kinda thinking if the bird has functional feathers and is in a dry, draft free, coop it can probably make it through winter weather in most areas. Of course comb size is something you could base cold hardy off of because frostbite is more common for them but I have never seen comb frostbite kill a chicken and it is usually only a first year thing for my birds.
Let me know what you guys think.
