Hello im new to BYC and i have had one of my silkie's die of a mysterious disease. She wasnt really active when she got the disease, then it got worse. One day I found her not moving in the corner of the coop. We quarantined her and the next day she died : ( . I have a theory that a rat got her sick. Recently I have killed a rat that came to the coop at night. A few days later, One of my other silkies got the same symptoms my dead silkie had. I am scared for the health of my flock and i thank everyone who helps. thank you.
