My Light Brahama chicks are pasting, and I'm worried that I've just traumatized them! I didn't realize it was even an issue until today when my hubby and I saw a few with quite a bit of "build up" around their vent areas. We tried wet paper towels, but couldn't make the clumps soften, so we used mineral oil. I dried the chicks as well as I could, but I'm worried that they're going to be cold with their damp, oily little backsides. Will they die from having oily backsides??
