[1] According to PopMatters, the style of Cockadoodledon't is defined by the Legendary Shack Shakers' detours from the album's overall sound,[4] which The Cleveland Scene said sounded like "if Tom Waits, Southern Culture on the Skids, and the brain trust behind Ren and Stimpy holed up in Johnny Cash's country cabin with an ample supply of beef jerky and moonshine".

[2] AllMusic said that the album was defined by "horror-movie vocals by frontman 'Colonel' J. D. Wilkes straight out of the Lux Interior school and a hardcore, ragged combination of frayed blues, twisted bluegrass and ornery swamp".

[4] The album was reviewed by Stephen Haag of PopMatters.com, who concluded "All-at-once reverent, revisionist, greasy, and fun as hell, with summer upon us Cockadoodledon't should be the soundtrack to a thousand barbecues.

"[4] Bob Gendron writing for AVguide stated "A mind-blowing assault on bluegrass rhythms, cowboy country, roadhouse blues, and sweaty rock and roll fury, Cockadoodledon't makes Reverend Horton Heat sound like The Eagles.
