i am looking to process about 6 bantams but the thing is my gram's isn't going to be able to help me with the neck cutting so i was going to use an axe but i scared of missing the head if they move at the last second any suggestions?
Some people use large pruners to cut off the heads and that would certainly work well with bantams. Or you could just hang them upside down, either in a modified plastic jug nailed to a tree or fence or by loops of cord around the feet, and just cut the heads off with a butcher knife. Bantam heads come off very easily and all you'd have to do is hold the head in one hand, cut the neck with the other.
YouTube has many, many good vids on how to dispatch chickens and it may help you to watch them and get an idea of what method you'd like to try.
