Chickens lay a rainbow of colors when it comes to egg shells. White, cream, tan, pink, blue, green, brown and speckled. But did you realize that a chicken’s earlobes are different colors as well, and that some people can make guesses as to what color egg a certain hen will lay based on her earlobe color.
A chicken’s ears are located on each side of its head, just below its eyes. They do not stick out like most animals do. The ears are located inside of the head. The earlobe is just below the ear. It is a slight thickening of the skin and is smooth with no feathers.
Birds are the only animal that lay colored eggs. Popular folklore says that if a chicken’s earlobes are white, they will tend to lay white eggs. If they have red earlobes they will lay brown eggs. We know that there are many exceptions to this. Some red earlobed birds lay greenish or blue eggs. Silkies have turquoise earlobes and lay a cream colored egg. Chicken breeds which have white earlobes with a pearly iridescent shine such as a cream legbar, lay blue eggs.
Eggshell color is definitely based on breed. Unless you have a mixed chicken, the birds will lay true to their breed. Araucana have red earlobes and lay blue or green eggs. Penedesencas have white earlobes and lay dark brown eggs. Some Americanas have white earlobes and lay blue eggs. Earlobe color is based on breed genetics as well. You can’t correlate earlobe color and egg shell color because one is not based on the other.
Depending on the breed, a hen will lay about 500 eggs in her lifetime. All eggs start out white. Those that are other shades have pigments deposited on them as the eggs travel through the hen’s oviduct. This journey takes about 26 hours until the egg is laid. The shell itself takes 20 hours to complete. Ameraucanas have the pigment oocyanin deposited on the egg as it travels. This pigment permeates the eggshell resulting in both the inside and the outside of the shell being blue.
Chickens that lay brown eggs deposit the pigment protoporphyrin on the eggs while they are forming their shells. This pigment only stays on the top of the shell. The inside of the shell remains white. The darkest brown eggs are from Marans.
In order to create a green colored egg, a brown pigment overlays a blue egg shell. The darker the brown pigment, the more olive color the egg will look.
No matter what color the outside of the egg is , the inside will all look similar. The color of the yolk is determined by the hen’s diet. The more green veggies in the diet, the deeper the color of the yolk.
Chickens have two ears on each side of their head. They have eardrums and an outer ear, middle ear and inner ear. They are able to harness sound waves and send them to the inner ear. Unlike humans, who experience hearing loss as they age, chickens are able to regrow damaged hearing cells. Scientists are very interested in learning more about this special adaption and in being able to apply it to help humans with hearing loss.
Hearing well is very important to all birds. It is imperative that they can hear approaching predators. Chickens can tell how far away a sound is coming from by gauging how long it takes the sound to reach the ear.
Baby chicks are able to hear their mother clucking from inside of the egg. An embryo can hear by around day 12 of their incubation period. Once hatched a chick will respond to its mother tapping on the ground when she finds food. If you tap on the food dish your baby chicks should come running.
Ear infections in chickens are often caused by bacteria entering the ear. Antibiotic drops can be given for 3 to 5 days if the infection is caused by bacteria. Clean the ear with hydrogen peroxide and a Q-tip to loosen any debris on the ear. Do not put a Q-tip deep into the chicken’s ear as it can damage it.
Timely egg collection is important. Don’t leave eggs under hens unless you plan on hatching. I like to use a wire egg basket to help me handle all of the eggs if find. If you are interested in more information on egg collection check out our blog.
It is fun to see the assortment and variety of egg colors that can come from your hens. You can display them quite creatively with an egg spiral holder or egg counter holder. Eggs that have not previously been refrigerated can stay on your counter for about a week and stay fresh. You can get quite fancy with your egg storage holder.
