With most animals, it is relatively easy to determine the sex of the newborn. The male reproductive organs are located on the outside of the body and are relatively easy to see, even in newborns. This is not the case with poultry. In male birds, the reproductive organs are inside the body cavity. This makes sexing newly hatched chicks difficult.
Vent sexing day old chicks is a skill that takes a long time to develop. It involves holding the chick upside down in one hand, expelling the fecal material, and everting (turning outward) the vent area. The producer can then look for the presence or absence of a rudimentary male sex organ. This process sounds much easier than it actually is. To accurately sex chicks in this way, you need to be well trained and to have had a great deal of practice.
This is the most accurate method for improved Kienyeji chicken.
Feather sexing is only possible for some chicken breeds.
Myths and Old Wives’ Tales
- It is a common misconception that you can candle an egg to determine whether it is fertile. You cannot candle an egg and determine whether it is fertile. If the egg is fertile, you can’t determine whether the embryo is male or female
- Another myth involves observing the shape of the egg. According to this method, eggs that have a longer, narrower shape will yield male chicks, and eggs that are rounder will yield female. In reality, the shape of the egg is not related to the sex of the offspring, nor does it indicate whether the egg is fertile.
