You’ve read our article about steps to take to start raising your own chickens and now, with Easter right around the corner, you have EGGS on your mind! Chicken eggs come in a myriad of colors.
Each chicken breed has specific genes that affect eggshell color. Chickens that lay colored eggs include Barred Rock, Rhode Island Red, Welsummer, Maran and Easter Egger hens. No matter the color, hens need balanced nutrition to lay eggs with strong, protective shells. Purina® layer feeds include the Oyster Strong® System so all the calcium hens need is in the feed – no need to supplement.
Colored television may be commonplace today, but can you imagine the excited chatter as families witnessed it for the first time in the 1950s? The same holds true for farm fresh eggs. Colored eggs are trending in the backyard chicken world, from olive to blue and speckled to chocolate brown, .
Collecting farm fresh eggs becomes that much more fun when the shells are shades of the rainbow. That’s why many chicken raisers keep a variety of breeds. Just remember, no matter the shell color, a hen needs calcium in her layer feed to lay strong and stay strong.
Chickens that lay colored eggs:
Eggshell color is unique to each hen, depending on her breed and genetics. Eggshell color does not change egg nutrients; the color of the shell is simply decoration. Popular breeds that lay colored eggs include Barred Rock, Rhode Island Red, Ameraucana and Welsummer chickens.
You may be able to tell the shell color by the hen’s earlobe. Hens with white earlobes typically lay white or lightly tinted eggs. Hens with red earlobes most commonly lay brown eggs, but there are always exceptions to those rules. Different shades of eggshells can come from the same bird on different days. This is because the bloom, put on right before the egg is laid, contains a fair amount of pigment.
A hen will not change eggshell colors throughout her life; although, toward the beginning of a laying cycle the hue may be darker than towards the end of the cycle.
Some chicken keepers discover even more unique egg colors, like deep pink, dark green or speckled, by crossing different breeds. When a hen and rooster are mated, genes from both parents contribute to the eggshell color laid by their offspring.
Some of the most popular crosses are called Easter Egger or Olive Egger chickens. Easter Eggers can lay a variety of egg colors, from blue to green and sometimes even pink. Olive Eggers are aptly named for the olive-colored eggs they lay and are a result of crossing brown egg layers with blue egg layers.
How chicken egg colors are laid:
All eggshells start white inside the hen, because shells are primarily calcium. If your hens lay colored eggs, look at the inside of the shells to see the importance of calcium:
- White eggs will be white all the way through
- Brown eggshells will be white on the inside
- Blue eggshells are blue all the way through
- Green eggshells will be blue on the inside and green on the outside
Pigments called porphyrins are secreted from cells within the hen’s uterus to add color as the hen forms the shell. Blue egg layers add pigment early in the shell formation process, which is why these shells are blue all the way through. For instance, a combination of blue and brown pigments produces a green shell color, as with an Olive Egger. Hens that lay white eggs do not produce any pigments during shell formation.
Hens need approximately 4 grams of calcium per day to form each eggshell. If a hen doesn’t consume the calcium she needs, she will pull the nutrient from her bones which can weaken her skeletal structure. Calcium included right in the layer feed is the best – such as Purina® Layena®, Purina® Layena® Plus Omega-3 and Purina® Organic Layer Pellets or Crumbles, which all contain the Oyster Strong® System.
Historically, chicken raisers have supplemented oyster shell on the side of layer feeds to provide calcium. However, this can create a lag between when a hen consumes it and when they need calcium to form strong shells.
Birds are good about regulating feed and nutrient intake, but it tends to take a few days before they will look for more calcium if needed. The Oyster Strong® System included in Purina® layer helps hens consistently get both small and large particle calcium in every bite, no supplementation needed. Calcium is steadily supplied during the full 24–26 hour egg formation process. This helps hens create strong, protective shells, no matter the color.
