My silkie hen has been sick for a long time. Her only symptom was diarreha but now when I found her today she was laying in the corner, practically just skin a bones she is so skinny, and she can barely walk. We have tried everything (such as worming multiple times) but she is just suffering. I feel terrible seeing her like this. Is there a way I can just put her down that doesn't include anything bloody or "graphic", if you know what I mean?
