Tray of many different eggs

Chickens make wonderful pets. From their aloof confused stares to their strutting teenager-esque walk just begging you to try to tell them what to do, having some hens clucking around the garden is brilliant.

On top of their quirky characters, the biggest advantage of keeping chickens is ... eggs!

Eggs that are fresher than fresh, with yolks as yellow as the morning sun and whites as pure as the driven snow (am I waxing too lyrical!).

A good laying hen, like a Black Rock, will produce an egg a day so it won't be long before they become a big part of your chicken keeping routine and life.

If you would like more details of how many eggs a hen can lay in a day, and which breeds lay the most eggs, see our blog on How Many Eggs does a Hen Lay.

Shell-less, Soft Shelled and Mis-shapen Eggs

Egg without shell

The laying of soft-shelled eggs can happen to both young hens, as they come into lay, and older hens as they stop laying.

In young hens, it happens as their bodies change to get ready for egg production, and in older hens as they reach the natural conclusion of their egg-laying period where the eggshells can become thinner and weaker and therefore deformed.

In both these instances, the laying of softshell eggs is fairly common, but in a middle-aged chicken, it can sometimes be a sign of a calcium deficiency.

A calcium deficiency in a hen is easily solved, through either giving your hens Oystershell Grit to peck at, or through using a calcium supplement, like Flyte so Fancy Cal-Boost Poultry Calcium. Cal-Boost is a concentrated calcium supplement with added vitamin D3, which when added to drinking water will help improve shell strength, thickness and quality.

Equally, oyster shell grit and making sure that their feed is of good quality, and well-known feed, will help keep eggshells strong.

Eggs with mal-formed shells

More common than a softshell is for an egg to have a thicker band of shell around its middle.

This is usually formed when a shock stops the egg in place. Extra layers of calcium are then deposited around this band before the egg moves on. While fine for eating, these eggs shouldn't be used for hatching or selling.

Wind eggs or cock eggs are very small eggs, with no yolk at all inside, just egg white. The opposite is what is called a double yolker, which is the reverse where there are too many yolks in one egg. Neither can be used for hatching.

There are other reasons that a hen might be laying a soft-shelled egg. It can be something as simple as your girls are not getting enough daylight. Whilst they like somewhere dark to nestle down to actually lay an egg, they need to get plenty of daylight to get going, and to keep laying.

Convention says they need approximately twelve hours of daylight to produce an egg. Obviously, during the short winter days, your hens might go off lay, however, if your run or pen has a dark or black roofing on it, causing your hens to be in deep shade all day, this might have enough of an effect to stop them laying. A translucent roof covering is ideal.

Equally some diseases, such as infectious bronchitis, can cause soft-shelled eggs. A trip to the vet and some antibiotics can usually cure this, but obviously, if you're using eggs for breeding, then eggs from the infected hen should not be used.

Perhaps, rather than getting soft-shelled or deformed eggs, you are getting none at all. If the bird isn't too old or too young for laying eggs, then (as silly a question as it is) is your hen actually a hen? Through ignorance, poor sexing or deception, it's possible you have been given or sold a cockerel by mistake, therefore no eggs.

Lastly, diet plays a big role in egg production. If a hen is fed too much of something that is bad for them, for example, excessive amounts of treats, greenery, or a high protein feed, the bird can quickly become obese and stop laying.

Egg Washing

Happy Eggs

Keeping a clean and tidy hen house is often the simplest and easiest way to keep your eggs clean from the get-go. But, no matter how clean, things can get a little bit grubby sometimes.

If your flock is just a few hens in the backyard then a quick rinse under the tap will get your eggs clean.

However, eggs should never be left to soak in water. Due to its porous nature, the eggshell will draw in the water, as well as any bacteria with it.

To ensure that you kill off any bacteria or germs, then a good egg washing liquid will get the job done. Chicktec Egg Wash can be used for either hand washing or in a machine and has been proven as highly effective for cleaning eggs.

Net-Tex Ready to Use Steriliser & Egg wash is designed to kill the hardiest of bacteria and it is merely a case of giving each egg a quick spray, leaving it and then giving it a quick rinse off. Both of these are highly economical, a huge bonus if you are only getting a few eggs every day.

If you are planning on incubating eggs for hatching, then washing the eggs is important, as well as sterilising the incubator. Chicks from unsterilized shells tend to be sickly and not live as long.

DEFRA guidelines won't apply to many of us with only a few hens in our back gardens but it is useful information to know. Egg Marketing legislation does not allow for Class A eggs to be washed.

As we understand it, the feeling behind it being that eggs of this grade and quality should be clean enough already. Class B eggs and those for processing are ok to be washed.
