I have a young Buff Roo that is ill. Have tried everythig to help him. I don't think he is going to "make it". We are both miserable. If I have to put him down are there any suggestions as to how to do it. There is NO WAY I can break his neck. I had an Aunt that raised parakeets and if she had to cull one she would put it at the exaust pipe of her car and let carbon monixide put them to sleep. Has any one ever done this with a chicken ? Suggestions PLEASE !
