IMO, and not using that method myself. I would think it would work just fine for a Banty of that age.
I would not however use that method on say..... a year old rhode island red.
Your chicken has lived a fine, if not great life, so now it has 2 bad seconds. And, I do not mean
that coldly. I just think of how the rest of our food is treated. When I butcher and it bothers me,
I just pretty much think of how the pig that created the bacon from yesterdays breakfast was treated.
And that really really bothers me. As pigs are even smarter then dogs. So, when we humanely cull
out our livestock.......... it is what it is, and I am glad we are all trying to make it as easy as possible.
I also have rabbits, and have a tool built for me to make that as easy as possible.
the lady w/4 dogs, 4 city chickens, 4 meat rabbits, their kits, a lizard and a kitty the dogs found who will
go to his new home in 2 weeks............ yeah!!! for him.
