Cool article GP.
I was poking around for scale options (I think I want more than one type down the road) and came across world record weights for chickens:
"Weirdo" 22 pounds extremely aggressive rooster that killed cats and attacked dogs. White Sully. 1970s
“Big Snow.” He weighed 23 pounds and 3 ounces. White Sully. 1992
"Big Boy", CornishRockX, official live weight of 24.18 pounds. Standing approximately 15” at the shoulder, "Big Boy’s" upward reach was well over 20” and his body girth was around 28 inches. 2012
The White Sullies seem to have been extremely active despite their size and super aggressive, like guard dog aggressive tear through wire cages to get at target orf their attack, dogs, cats, other roosters...
Anyway these are the big boys I guess in the record books.
