So a few days ago one of my silkies fell ill and died. We didn't know what was wrong but she had always been kind of sickly and she passed peacefully in her sleep. I thought it was an isolated case. Then yesterday we went out to check the coop and one of my wyanndotte pullets had died randomly. We weren't watching her for illness or anything, she didn't show any signs or symptoms. Now today another one of my wyanndotte pullets is ill. We found her in the coop shivering. She's standing up really tall and stretching her neck out. She doesn't appear to be gasping for air. She's also drinking lots of water. We have since separated her and moved her indoors. She's now showing no interest in standing but still has her neck stretched out. When we pick her up she goes almost limp in our hands like she's dead. She doesn't appear to have any respiratory issues. Any help you can give would be great. I'd really like to save her but I'm worried it might be something that could spread to the rest of the flock. Thanks.
