Usually an Egg Includes One Yolk and the Egg White, But Sometimes, the Egg will include Double Yolk. A Double Yolk occurs in an Egg When a Chicken Releases Two Yolks into The Same Shell. Double Yolks are Usually Produced by Young Chickens. But, Just One, Two or Three Out of Hundreds of Eggs From Thousand Chickens. Since Their Reproductive System has not Fully Matured, So They Periodically Release Two Yolks instead of One. These Are Perfectly Safe to Eat But Not Good For Hatching Purposes.
If You Found Such Twins inside Your Flock, Don't be Panic. Just Carry On the Same Management.
Don't Think About Excess or Deficiency of Calcium or Change Diet, Because as Soon Their Reproductive System will Mature, Hens will Start Laying Normal Table Eggs.
