"Justin Rhodes" is one of those channels that make me wonder where they find all the idiots that have the time to watch a self-satisfied @-hole like that, This was probably more of a gross stunt to get more views (and shares). His chicken tractor was a much better idea, but then it's not exactly free range anymore...
If a chicken farmer would do something like that over here , he would not be selling a lot of eggs if word got out, and he'd get big trouble with food safety authority...

the mealworms OTOH are a great idea, good source of proteine, and you don't have to hang a cadaver in your chicken coop :-)
