16 days old chick completely stopped eating today. She almost got thrashed by the rest of the chick before I separated her from the flock. Now she's constantly chirping to get under mom. She was eating less than others during the past three days. She had impacted crop around a week ago. Since then she has shrunken while the others grew a lot. I thought she'd recover but seems like she's dying. Poop is alright. Gave her electrolyte water regularly. What else can I do for her?
