How big was this bird? I usually let my DP roos grow up a bit more than 12 weeks, they're not worth the trouble to butcher until at least 18-22 weeks. Also, at that young age they're growing in a bunch of feathers, no wonder there were so many spiky pins. But those can usually be scraped off with a dull knife, rubbed across the direction the pinfeathers are growing in.
I agree with the other posters, sharper knife, cut lower -- just behind the point of the jaw bone, where there is just skin, not feathers. And nice hot water, around 150 degrees, agitating & swishing the bird up & down to get the water down to the skin. When a wing feather sliiiides out real nicely, you're ready to pluck. And it should go as easy as wiping the lint out of your dryer trap, not like pulling grass!
I don't know what to tell you about the smell, I think it bothers some folks more than others. I do use disposable gloves for both plucking & gutting. Sometimes I'll put a pair of cotton gloves with the rubber gripper dots on over my rubber gloves & that helps the hand-plucking go even easier.
I hope you enjoy your chicken dinner after all this trouble & fuss!
