I never 'get' people saying skinning is easier. May be simpler, but man it's a workout for me. GF and I did her 9 roosters a couple weekends ago and I could sure feel it the next day.
It's "easier" for me since I don't have to fool with getting and keeping water hot. With my set-up that's a pain plus a bit of a fire hazard. My wife wants them skinless anyway.
If you are skinning baby Cornish X at 8 weeks or even relatively young pullets up to 7 or 8 months they're pretty easy to skin. But if cockerels hit close to five months that connective tissue makes it a good workout. A fully mature rooster, plan to cut a lot of that connective tissue.
