With a breech it is even more important to make sure their airway is open. Often when the umbilical cord is broken during a breech delivery, the lamb may take a breath and aspirate the birthing fluids. We want to make sure the airway is open and most often, as this one did, they will sneeze out some of the fluid.
Birthing is a bloody mess. It is amazing to me that the breech baby is white while the 1st born here is yellow. She won't be for long! Mom will make sure of that.
