Calcium depositsĮxtra calcium deposited on areas of the eggshell. Lots of gaps, marks and other imperfections in the shell’s surface and shape Pointy eggĪ pointy or elongated shape to the egg. No calcium has been laid around the yolk and albumen to form the hard shell. The result is a range of different shell abnormalities, most of which don’t require discarding the egg. Here are some examples of eggs that have encountered different issues as they have traveled through the oviduct. Fortunately, Salpingitis is fairly rare and something I have only seen once in my five years of egg farming. Technically called Salpingitis, the Lash egg is certainly not for eating as it is comprised of pus, tissue and pieces of egg matter. A Lash EggĪn infection and consequent inflammation of a hen’s oviduct can sometimes cause what’s termed a “Lash” egg which is not really an egg at all. The egg’s shell construction, which happens in the Uterus or Shell Gland, takes a whopping 20 of the 25-hour egg production process! It’s no wonder that we see such variation in shell colour and condition when the shell takes so long to build. Hen OviductĪs the egg is built over the 25 hours needed to complete the five different sections of the Oviduct (Infundibulum, Magnum, Isthmus, Uterus, and Cloaca), a lot can go wrong.
These are all the result of something interrupting or affecting the production of the egg in the 80cm long Oviduct where the egg is constructed. The second most common eggshell problem is rough or deformed eggs.
#MISSHAPEN CHICKEN EGGS FREE#
Here are just some of the likely colour variations you will find with free range chicken eggs! No such problem for fully-enclosed hens who have no predators, an optimum 21-degree shed to live in and minimal exercise. Extremes in temperature, stress from a visiting fox and the extra exertion from running about the backyard or out in the open. The reason for this is that free range hens have to cope with a range of different extremes at various times in their lives. One of the perceived benefits of “factory”, cage and barn systems is the environmentally controlled enclosures which enable greater uniformity in shell and yolk colour. Hens in a more free-range environment will tend to have much whiter egg shells and greater variation in yolk colour. The most common egg shell “problem” in backyard chicken eggs is colour variation. Luckily, most are purely aesthetic and don’t often mean that the internal quality will be poor. There is a range of different egg shell problems that you can find with your chicken’s eggs. On the inside, is the egg white or albumen which supports the yolk. The outer, hard shell is made of calcium carbonate and is porous to allow air and moisture to pass through it. What are chicken eggs?īasically, chicken eggs are comprised of three main structures with a number of sub-structures that support them. I have included a shortened, edited video of the presentation at the end of this post. The presentation focused on the many, common issues that affect the quality of chicken eggs and consequently, your enjoyment of them.
The following information is based on our, monthly “Eggucational” presentations This presentation was done on 27 November 2016. In this post, we look at issues that affect the quality of the external, shell condition along with the internal, edible portion of chicken eggs. There are also a huge range of factors that can influence the quality of a chicken egg.
Chicken eggs come in all shapes and sizes with no single one identical to another.
