We lost our dear Australorp Harriet on Wednesday. I had initially posted about her here . Harriet rapidly deteriorated despite treatment and multiple veterinary consultations, and we had to put her to sleep. We still don't know what it WAS that caused her illness, but we ordered a necropsy. Anyway, I swear Harriet's sister, Gertie, is in mourning. Our girls free range in our backyard, and Gertie has started to periodically visit the coop throughout the day as if she's "looking" for Harriet. She also just LOOKS sad to me. We've never lost a chicken before, so I don't know how flock mates generally react to a loss. Can anyone share their experiences with this? I could just be paranoid now, as I've spent the last three months staring at the chickens like a hawk while Harriet was sick. I could also just be projecting my own feelings onto Gertie - I'm pretty broken up about the loss. I never expected to get so attached to my flock.
