If you are a seasoned chicken owner you may know by now that no two eggs are the same. They range in size, color and shape, and at times you might even encounter what we like to call an ‘egg oddity’, which will often leave you scratching your head.
However, these seemingly strange occurrences can be explained, so continue reading below to solve the puzzle of your extraordinary egg.
Body-checked eggs are those that are wrinkled or assessed in appearance. This is due to them previously being damaged while in the shell gland pouch, often from stress or pressure put on them. They are then repaired before lay, which is what gives them their somewhat rippled appearance.
While this sort of egg may appear alarming, a shell-less egg is a seemingly common occurrence, especially in young layers, because their systems are still warming up to the laying process and their shell gland is still maturing. However, if shell-less eggs are occurring in your older hens, it might be a symptom of calcium deficiency (and overall poor nutrition), stress, infectious bronchitis, or EDS (egg drop syndrome). If it becomes a repeat issue, make sure that your cows are comfortable and eating a well-balanced, calcium rich diet. A quick visit to the vet to test for any further health issues will not hurt either!
Also known as”slab-sided”, these eggs appear to have a somewhat flattened side with wrinkled edging, and are more common in young layers. It gets its misshapen appearance from being kept too long in the shell gland, or in certain cases when a mis-timed egg proceeds down the oviduct and ends up resting alongside it.
Rough Shelled or Pimpled Eggs
Eggs that have differing textures can be due to a range of things. Little bead like growths on an egg (can be in a cluster or larger mole shapes), are known as calcified substance and may be a result of excess calcium intake, disease, or defective shell glands. If these kinds of eggs are only found infrequently, there’s absolutely not any cause for concern, however reducing calcium consumption over winter can help keep pimpled eggs at bay.
Uneven shell colouring are simply the result of uneven pigmentation while at the shell gland pouch-no cause for alarm!
Egg Within an Egg
Theres nothing more alarming than cracking an egg into your frypan and seeing there’s another whole egg inside of it! But consider yourself lucky if this happens to you, as it is a remarkably rare occurrence! Known as counter-peristalsis contraction, this bizarre event results from the early launch of a new yolk while a present egg remains in the formation stage and not yet been laid. This then causes a contraction where two eggs meet up in the reproductive tract and provided a layer of albumin, membranes and a shell surrounding them both prior to being laid! While this might seem disturbing to some, it doesn’t in any way mean your chicken is unhealthy.
Blood spots can appear on the surface of an egg yolk and is the direct result of a blood vessel breaking in the gut as the yolk has been discharged, or in the oviduct as the yolk travels through it. They occur more so in older hens that have a genetic predisposition, are deficient in Vitamin A, or can also be a completely random occurrence!
Also known as”rooster eggs” or”wind eggs”, super small and yolkless eggs are often produced by young layers using an immature or non-synchronized reproductive system. Or in an older hen, as the result of a piece of tissue in the reproductive tract breaking off and being treated as an egg. They have the exact look of an egg, complete with a shell, but without a yolk-what a joke!
Double Yolk Eggs
Our favourite sort of eggs-double yolkers occur when two separate egg yolks are discharged into our hen’s oviduct too close together, and so end up becoming encased in one shell. This can be due to a hormonal change or imbalance which releases the yolk too early. Double-yolked eggs are more commonly produced by new layers, or those nearing the end of their laying life, and is often a hereditary characteristic. These eggs are usually much physically larger than eggs to accommodate two yolks, and doubly yum!
These are simply a few of the well known ‘egg oddities’, if you’ve encountered any extraordinary eggs we’d like to hear from the comments!
If you’re worried about continual or replicate problems with your eggs, it is ideal to go to your local vet to check about your chickens’ health.
