I wouldn't call this an emergency but my hen Joy is clicking her beak almost like she is nibbling at grit. Could it be symptom of any sort of disease or possibly depression? She is also obsessively grooming herself and I am not sure if this is because she possibly has mites or because she finished molting a couple weeks or less ago. Has anyone heard of chickens grooming obsessively because of depression? (almost like cats).
I ask the depression part because her only other coop-mate and best friend, Willow, passed away yesterday for no apparent reason. An hour before she passed away she did not race out of the coop like normal, rather she stood tall with her legs splayed on the roosting bar (according to my mother). An hour later we found her dead on her side in the coop, seemingly asleep––eyes closed peacefully. She had been eating and drinking with normal consistency and she had as much energy (a lot) as she usually had.
Anyway, does anyone know symptoms of depression for chickens, and is grooming/clicking one of them? I don't believe she is having trouble breathing, so I don't think she has a respiratory issue. Also, has anyone experienced sudden death in their chickens? (she did not die of old age, she was 1 this past july).
