One thing that will make an impression on them is to make sure they see the culling process from a distance. They do understand death.
None of my poultry will come within arm's length of me. That is partly due to them knowing what usually happens if I get my hands on them. They have seen too many of them permanently disappear after I get hold of them. Some leave to go to new homes and some get processed.
Even if you start all over, if you raise the new ones the same way they will learn the same behaviors.
I have found the Sweetgrass turkeys that I raise to be the most mellow turkeys of all the varieties that I have raised.
