Decapitation and cervical dislocation are both acceptable, humane slaughter methods for birds, at least here in Canada. Stunning is generally required for larger animals, and for some other methods (like it should be used on geese and ducks if using the broomstick method) but birds that are being killed by chopping their heads off do not need to be stunned prior. I agree that attempting to stun a tiny bird is not going to work well with blunt force trauma, which seems to be the only option, as I’m sure none of us have the equipment to use electric stunning. Lol. I read through the entire handbook on euthanasia and humane slaughter from the CFIA prior to getting any of my animals so I was equipped to deal with it, but now I don’t know that I could kill them. Haha. We’ll see, considering I wound up with what looks to be all boys...
