Thought this might interest some new to poultry+ I am bored!

ear lobe color: most fowl have red lobes, many have white and some have turquois. The red color is due to many blood vessels which are close to the surface, squeezing may cause blood to be disgorged. Insect bites readily leave blood bumps on the surface. White and blue lobes is a polygenic trait(caused by several genes)and is purine pigment which effects the surface color. as some birds age the white is decreased showing more red; damage can also leave red areas.Each breed has a desired color of ear lobe according to the breed standard. Even the shape and size of the lobes are designated by the standard. Ear lobe color has NO connection to the egg shell color.
