We have a dear little cochin hen who has an impacted crop. We tried everything and it is more than a week and she is going downhill and is obviously suffering... We usually just use a machete to cull birds, but this little one is different... she is such a sweetheart and has been a joy to us. I can't bear the thought of putting her down the usual way. Does anyone have a recommendation for putting Sonnet to 'sleep'. It seems a little crazy I know, but I am really sad and want a peaceful way to see her on her way to the big coop in the sky. Please help us...
