Not sure what all the fuss is about. In the past I usually have had about 6-7 chickens. With the exception of a playful puppy I took in earlier this year, Would miss maybe 3 a year, at MOST? I have 2 places, to house chicks until they are old enough to handle themselves outside. I live in S Central MT. Weather varies!
I've always let my chickens free range.
One winter I had a Barred Rock roost in a tree for DAYS, in >20 degree weather. One year, whoever sold to TSC, 2 died within months of purchase. There's an old computer table, banana boxes of kindling and a covered chest freezer on the back porch Most roost on. They're CHICKENS, they WILL find a place to sleep and WE ALL WASH....

I have about 16 pullets, hens, this year. Have a few people Hooked on the TRUE Orange yolk eggs, LOL. There's a special place the Grit and Calcium go, so they can free feed, 20 acres to roam and plenty of bugs. There are 2 wandering horses that provide bugs also. (Why some neighbors **tch, they're 'exceptions' to the State law?

Waterers all over. Thankfully, I adopted an abused, abandoned hound. If she smells ANYTHING on the property, she
OUT for it. I have wood boxes, front & back porches, 2 pick ups, trees & a few bushes providing shelter altho have only had 2 flying predators, that I recall.
IMHO, It's like manual/automatic Transmission vehicles; If you demand one, you accept the limitations of such. If you can do both, you B-R-O-A-D-A-N your abilities.
