this is the tool. You put the sharp side into the slit in the roof of their mouth and the other part on the top of their head. Apply force quickly. Then cut their throat. It should let the feathers come out easily and the immediacy of it is supposed to be painless or as near as.
I can't buy one here but I am planning to buy one or more online when I return.
you can buy them from that website
Using one of these and having the feathers drop off without having to heat and dip the rooster would make up the difference in my being able to process. Pithingis a way of life that people did for hundreds of years.
