We have this flock of White Chanteclers that, thanks to a rookie mistake on our part, got infected with some respiratory infection when we introduced 7 new hens without quarantine. Long story short, trying to find the most humane way to end their lives, we decided to gas them. We figure they fall asleep, they pass away in their sleep. Over 2hrs later they were still alive AND awake ! So today, hubby did what he had to do and wrung 20 little necks . Well guess what? Our big rooster is still alive and kicking. I saw my husband, who is not a weakling, twist that rooster's neck around. Then dropped it on the ground in the snow. The bird was not moving!! And there seems to be another hen at least still alive. I think we may have a bunch of mutants on our hands lol. At least we know they are a tough breed, that's the only silver lining .
