Why are some chicken egg shells very thin?

Calcium deficiency One of the most frequent causes of laying thin shell or soft eggs is a diet low in calcium. While most quality layer feeds have extra calcium in them, you should still offer a supplement just to make sure your hens get enough.

How do you make chicken egg shells thicker?

The best way to give your chickens a calcium boost is to introduce shell-grit into their diet. Shell grit is made up of calcium rich oyster shells/cockle shells and/or limestone, and should be put in a separate feeder to the normal layer feed for your chooks to peck at.

Is it OK to eat an egg with a thin shell?

If your birds have been in production for several years, soft or shell-less eggs may be an indication of a mineral or vitamin deficiency, usually calcium. Finally, take care not to break a thin-shelled egg when collecting it from the nest box, and remove it from the coop as soon as possible.

What affects egg shell quality?

The quality of the shell depends on many factors including age, genetics and nutrition, as well as environmental factors (cage types, lighting programs) (Dunn et al., 2009; Nys, 2017). In particular, the quality of the eggshell deteriorates with the age of the hens.

Why are some egg shells thicker than others?

The thickness of the shell is determined by the amount of time it spends in the shell gland (uterus) and the rate of calcium deposition during shell formation. If the egg spends a short period in the shell gland, the thickness will be less.

Why are some egg shells harder than others?

Older birds lay weaker shelled eggs and younger birds lay eggs with stronger shells. There is about the same amount of calcium in a small egg shell as in a large egg shell, so the smaller egg shell will be harder.

What is a good source of calcium for chickens?

Crushed oyster shells are an excellent source of calcium, and are the most common way flock owners supplement calcium in their flock. Some people also clean and crush their used egg shells and feed them back to their hens.

Why are some chicken egg shells harder than others?

As a hen ages, the eggs that she lays get gradually larger. However, the calcium content deposited in the shell remains the same despite the size of the egg. So, the eggshells become thinner as the hen ages.

Why are some chicken egg shells thicker than others?

How do you improve egg shell quality?

Increase in salt intake through the drinking water or the food is also known to reduce shell thickness and calcium absorption. Sodium chloride given in the drinking water reduces shell quality and increasing plasma calcium and phosphorus more than when sodium chloride given in the food.

Why are some eggs bigger than others?

Egg size is related to the age of the hen — as a hen gets older, she lays larger eggs. Eggs are sorted at the grading station based on weight, not circumference, and packaged accordingly into the following sizes: pee wee, small, medium, large, extra large or jumbo.
