My flock of four became three today when one of our hens was found dead. She was essentially the leader of the pack, and since one of our girls is losing some feathers and Lily (the one who passed away) enjoyed pecking her, I had separated her from the other three. She was roaming around until dark in our backyard when my dad put her away for the night with the others. While she was squawking a good bit, she's usually pretty noisy and none of the other hens displayed any change in temperament. My dad is proposing a snake bite, but there was absolutely no blood or anything. It was pitiful... Please someone let me know if they can guess at her cause of death! My hens are pets, so this is devastating, and I do not want a repeat! Could she have eaten anything poisonous??? It has been pretty hot, but they all have access to water, whether they are in the coop or not (We often let them free-roam.).
