hahahahah I am so sadistic! I think That was the most horrifyingly hillarious thing I've ever seen! and the title " Anyone Can Build a Tub-Style Mechanical Chicken Plucker" for a book? hahaha never thought I'd hear of a book by such a name!
I'm going to make one and on the side Ima paint "Naked chicken amusement park" lol because it looks like they're on a ride gone wrong at the carnival...
seriously though, that's a beautiful job, I am very impressed by your husband and it looks so much easier then doing it by hand! Can you put any size chicken in there? Just an idea for you, there is someone on CL renting their plucker for $30 a day or $50 for a week and they 'claim' it's rented pretty far out... there's isn't as nice as yours, maybe you could make and sell or rent these?
