After reading the comments and hearing advice from an old chicken man who's forgotten more than most about birds I chose to kill the sick birds in order to keep the rest of our flock healthy. While I hated to do so it was the right thing. In a day when many value the life of their pets more than their neighbors I was reminded of the time tested values I learned as a kid on the farm in central western Ohio. Animals are not people and vice versa, we can dress them in clothes and give them pretty names and talk to them like a new born child but truth be known chickens are chickens. Left alone in the right situation they would not think twice about picking the flesh from our bones. None of the culled birds suffered and my resposibility to my family, neighbors, and fellow chicken farmers was fullfilled. Times and people may change and though not always popular the best thing to do is what is right!
