Some of the game fowl breeders do not consider the size off egg when breeding. For them it doesn’t matter whether the size of egg is small or big. But the question is it really matters the egg size? Based on my experience, the size of the egg really matters because the larger the egg of the chicken its effect is it will produce a larger chick. And also, it is god to stock larger egg for incubation which it is better that the egg to be keep and later to be put in the incubator is 50 to 60 grams. How to produce large chicken egg? The WE cannot compare the size of chicken egg because it depends on the kind or breed of chicken which is game chicken lays smaller egg than a kabir or a layer. There are chicken breed like kabir who laid big or large size egg. But game fowl is different from broiler or layer chicken that is why we cannot compare their egg size.
The game fowl chicken, the hen start to lay egg at the age of seven months. At that age when the hen start to lay egg, the size of the egg is small around 40 grams. So, what the breeders do in order that the hen will lay bigger egg with a weight of 50 to 60 grams? The best thing to do is to let the chicken lay egg for several months then the breeder will monitor the size of the chicken egg until it can produce a bigger egg with a weight of 50 to 60 grams. The older the hen, it will produce a large or big eggs.
Based on my own experience as I breed game fowl, larger eggs are better compared to a smaller egg in incubating because there is a higher percentage of hatchability when the egg is big and also it will produce a bigger chick that is healthy and can survive later against the threats outside like bad weather condition. Bigger chick later has an advantage in terms of body and bone structure and also in height. That is why as a breeder I consider the size of egg in breeding.
