I'm new to breeding chicken and currently have 3 birds. Today, I noticed that one of the girls' is walking with a slight limp and weak. She was observed to be in a sitting position and unable to bring herself to standing position; I had to help prop her up. My other two appears to be fine. I'm unsure what this means. The guy I purchased the chicken from recommended that I end her suffering. Can any one chime in with suggestions on what is going on with my Golden Laced Wyandotte? Thanks.
