I ordered 15 chicks from a hatchery that had really good reviews. When I picked them up 2 were already dead in the box and 1 was almost died. The one that was almost dead had its eyes closed and kept opening and closing its mouth. In the last 30 min of her life she would make almost a clicking noise when she took a breath. In a matter of five days the rest of my chicks died the same way. I have never seen anything like this before. Has anyone experienced this? If so do u know what my poor babies were suffering from?
