A chicken laid an egg without a shell according to the Huffington Post.
"My chicken laid an egg without a shell," Reddit user Warlach said in a post on the site. "It only got weirder from there..."
According to The Poultry Site, eggs with very thin shells or no shells at all happen between 0.5 percent to six percent of the time.
While it may not be the case in the photo on the Reddit user's page, the eggs are often produced by young domestic hens, particularly by those that have matured early. Egg defects are one of the more interesting finds among animals because the situation with the chicken egg is different and eccentric, along with strange and frightening the Food Beat blog reported.
The egg with no shell is just a few of the unusual forms of the food product. Food Beast previously reported on others such as eggs with a double yoke, oversized eggs, and eggs inside other eggs.
Warlach's chicken laid other shelled eggs, but the unique one felt like a water balloon Food Beast reported. Although the egg's outer part did not have a shell the inside still had the ingredients of one. When Food Beast took off the thin outer layer of the the egg, staff found a large yellow yolk around an egg white.
Eggs which have very thin shells or no shells around its membrane appear to be very unattractive and can be damaged very easily the Poultry site reported.
Causes for shell-less egg include an immature shell gland, defective shell gland, disturbances causing eggs to be laid before calcification of the shell is complete, poor nutrition, saline water, and diseases such as infectious bronchitis or eggdrop syndrome.
