THE COCK IN ALPARGATAS: True or false? A hen needs a rooster to lay eggs .... and much more about the interesting 'World of Hens ...'

Posted November 24, 2017

The formation of an egg begins in the left ovary of the hen (unlike mammals, hens only have a functional ovary). The ovary contains many follicles and a mature ovum; follicle is the name of a pouch containing several eggs before they are fully formed. The mature ovum of the hen is what we commonly recognize as the egg yolk.

The development and maturation of an egg depend on a photoreceptor gland that is close to the eye of the hen. The hen needs to see 12 hours of light to cause an egg to mature.

From there the ovum passes through the five sections of the oviduct, where the different layers of the egg are added. The oviduct is a long tube connecting the ovary with the cloaca of the hen; the cloaca is the opening through which the egg comes out once it is fully formed. The oviduct is made up of the infundibulum, magnum, isthmus, uterus, and vagina; in each section an important part of the egg formation occurs.

2. The egg (or not) is fertilized ... in the infundibulum When the egg fully matures, it is released from the ovary and the infundibulum muscles encapsulate it. There the sperm of the cock can be stored: if the hen has mated, the ovum can be fertilized; if not, there is no sperm and the egg remains unfertilized. This stage takes approximately fifteen minutes.

3. The egg is added to the magno, the largest section of the oviduct, and stays there for two or three hours while the egg white is added. The egg white serves to feed the chick during its development (before it is born). If the egg is not fertilized, no chick can be developed, but the clear is added regardless of lack of fertilization.

4. The shell membranes are added ... on the isthmus

The last stage of egg formation is the latest: 20 hours or more. During this time the hen mobilizes 47% of her body calcium (from her own bones) to make the egg shell. This happens in the uterus, also called the calcific chamber.

Brief Fact: The round shape of the egg is actually the exact shape of the hen's uterus. The thickness of the eggshell depends on the amount of calcium the hen has available (nutrition), the amount of time the egg stays in the uterus, the age of the hen and the time it is laid ( oviposition). Some diseases can also cause irregularities in the shell.

6. The hen puts the egg ... through the sewer and with the support of the vagina

After about 25 hours in total development, the egg is ready. Go through the final section of the oviduct - the vagina - which has the only function of pushing the egg towards the exit. The vagina also secretes a substance called a cuticle, which seals the pores of the shell and prevents the entry of contaminants.

The hen has a single opening through which eggs come out and also digestive wastes; this is called the cloaca and has a division that prevents the eggs from getting dirty when they leave (although hens can easily foul them once they are in the nest).

Assuming that the hen has had sufficient exposure to the light, the formation of the next egg begins an hour later. That is, between egg and egg spend approximately 26 hours; so each hen lays her egg a little later each day, until she jumps a day for being too late. The cycle from the first day when you put your egg earlier until the day you jump is called the posture cycle.

How to know if you have a chicken hen

Normally hens take about half an hour to lay an egg. But it is possible that you will sometimes find a hen cast all day in an empty nest, or even on an egg that has just been put. If you stay for more than an hour in the nest, it is very likely that it is clueca. If the night comes and goes where it is, it is already a sure sign that you have a hen.

How to raise a hen

Of course, the first thing that occurs to a person without much experience is simply lifting her from the nest, perhaps frightening her a little. But it rarely works and most likely she'll wait out of the way until you leave and then she'll throw it out again. A hen that has decided to incubate eggs (regardless of whether there are eggs in the nest or not) is a very persistent animal and is a difficult task to dissuade. That is why it is convenient to change it; you will have to separate her physically from the nest for a few days. Putting it in another hen house two or three days should suffice. The important thing is that he can not see or reach his nest to throw back. Ideally you should make sure that she does not stress, because the more you stress, the longer it will take to put eggs back in.
