Big active adult call hen previous to brooding and her drake sold - This is the story/question: abandoned nest of eggs 4 days ago - was seen circling in pool (around, 'n around 'n around). I thought she was wetting her under carriage to moisten eggs. 3 days ago - confused look - too busy to watch for her. Has lost weight. Is now a Small hen. 2 days ago - 1 drop of pour on ivermec on neck skin; separated to 4 X 4 cage with water & food. Today - sluggish, cowering and weak. The end is near - why??? no toxins, poisens used; clean food & water daily; kiddie pool cleaned every other day WHAT is killing her???
