I read a thread from Siri search. It was discussing the broomstick method of killing. The person concluded she would use a cone. I made that mistake this year. I have a brand new cone. I was unable to get the birds head through the opening. My birds weighed 9 lbs at least live. I was so upset. Fortunately my brother happened to be here and we ditched the cone to hang the bird and stick it in the neck.. after that I concluded to grab the birds by the legs hang them . Pull as much skin forward of the neck bone and use a sharp sticking knife to go through the skin I bunched up, let them bleed out, then chop head off. At the beginning I grabbed them by the wings to put in the cone and that was traumatic for both myself and the bird.
