Had a calf born this morning. With the flies I decided to spray it's navel and butt with screw worm spray to keep them off. While I was at it I also sprayed her body lightly. Turns out the screw worm spray has a blue coloring in it. By the time I finished the poor little thing looked like a Smurf. Momma apparantly didn;t think much of the paint job since a little while later the calf was back to being red but with a bright blue umbilical cord
