I use an electric stunner. Don't laugh (or you can if you like

) but this is what I do. From the time they hatch I sing to them when I feed them, the same song every day. I sing to them when I catch them up the evening before slaughter and I sing to them whilst I'm hanging them upside down and doing the deed. I can honestly say I haven't had one bird panic.
When I do other people's I obviously don't sing and encounter widespread panic which is not nice for me or for the birds I'm killing.
Mad or not?

?

You can answer honestly.
