Info from my Rabbi friend:

Options:

1. He should freeze the boxed empire chickens solid and bring them in with him.
2. Or eat fish that are kosher and skip the chicken while he is there.
3. If he wants to kill his own chicken he has to hang them upside down so the blood will run out fast supporting the weight
Say the blessing thanking God and the chicken for providing for him and kill the chicken with
a knife so sharp it can cut a piece of paper that falls upon it.
The cut is on the neck so to spare the chicken suffering. The cut causes death instantaneously.
Jews don't eat animals that suffer, one quick cut with absolutetlyy no strangling or holding its head and spinning it around
like the mexicans do to break its neck.
4. Hold the chicken's weight while it is upside down before hitting the neck in a quick slice.
