Ok, but to those of us new to chickens, is there a set of criteria that wou would look at to determine if culling is necessary? What if the owners are unsure? I know with my dogs, as my girl starts to get older, we have actually had the discussion, and set a three point "checklist". We have identified her three favorite activities, and when she can no longer do two of them it's time to start the discussion. I think everyone knows that allowing suffering to continue is wrong. Sometimes, in animals that aren't "family" it's hard to tell. I know when my pups are in pain, but how would you judge that in a chicken??
