Congratulations on a successful operation ! Easier than you thought, huh?
. 38 lbs ! Wow, what a large dress out. That will take a while to roast. There is only me and my hubby so my largest dressed at 27 lbs. Lots of leftovers, sandwiches, soups, and casseroles for us for quite a while.
You did everything perfectly. Scalding does make plucking so much easier with the only risk being "possible" skin tearing while plucking, but when the water temps are just right it's a non issue.
In case it helps you when you do this again and want to retry dry plucking. Dry plucking works well when the bird is still warm after dispatching. It makes a difference when you use a twisting motion and pulling against the grain at the same time. Don't grab too many feathers, just a few at a time and work quickly. Wing feathers should be done first one at a time with the twisting motion as the wings cool off the quickest. I never worry about the wing tips and just cut them off because there is not much meat on them anyway.
I dispatched 3 this year. I scalded the first two and dry plucked the last one. Now that I got the hang of it I like the dry plucking much better. There were are few feather shafts that came out easily with tweezers while running cold water over the bird to cool it down after processing.
