Come jumbo eggs from large chickens

Size of chicken eggs

Even during the hatching of a small hen, the facilities in the ovary are set for a very specific number of yolks. So it is already preprogrammed for each individual hen how many eggs she will lay in her life. The size of the future eggs is also largely determined at this point in time. The decisive factor here is primarily the breed. Of the However, the size of the hen cannot automatically be deduced from the size of the eggsthat she will lay.

Lots of eggs vs. large eggs

Another factor that determines the size of the chicken egg is when it is laid. To at the beginning of the laying period there are numerous eggswho lays a hen, but by no means the largest! After the one year, when the moulting takes place, it begins second laying period with consistently larger eggs. On the other hand, the eggs are less numerous in the second season. Why is that? Does the hen’s organism have to get used to egg production? The explanation is much more banal. Everything is once again related to securing one's own species and is genetically anchored.

In the wild, it is already a great art for a chicken to survive until the age of 5 to 7 months is reached. So hens that have made it this far are immensely important for species conservation. A corresponding number of eggs should now be laid - as long as no predator comes and ruined the plan!

If the first laying period is "survived", the hen has already successfully reproduced and has contributed to the conservation of the species. In the second year, reproduction is also important, but the main focus is in the first year of laying, true to the motto “what you can get today, don't postpone it until tomorrow”.

Big hen big eggs?

If you take a look at the size distribution between egg and chicken, you will notice that one Big chicken doesn't necessarily have big eggs too lays! If this plan worked, the biggest chickens like Brahma, Orpington or at least Jersey Giants would have to lay particularly large and heavy eggs. Here, however, one encounters an egg weight of around 55 to 60 grams, which is not an extraordinary masterpiece in view of the weight of the hens from 4.5 to 5 kg.

It becomes much more impressive when we look at the egg weight of some breeds of bantam, such as the German dwarf chicken or the Bielefeld dwarf chicken. At around 1,100 grams, the hens bring eggs into the nest that weigh between 40 and 45 grams. All sorts of things for these flyweights!

The giants among the chicken eggs

Not every egg is the same and even with a genetically pre-programmed size, slips can occur every now and then. So it is not uncommon for hens that usually lay eggs of normal weight to please their keepers with a real giant. Such Eggs can easily reach the 100 gram mark crack.

Often these eggs are outside the norm and not only unusual from the outside! The inside also has a surprise - a double or even quadruple yolk. Especially in young hens, when the hormonal system is adjusting to egg-laying, double yolks can occur more often. Instead of just one yolk, several yolks leave the ovary at the same time and are packaged together. It goes without saying that the packaging then has to be bigger than with just one yolk!
