How Do Chickens Lay Eggs Without A Rooster?

Laying egg without rooster.

As incredulous as it may sound, roosters are not as necessary as they seem for hens to produce eggs. In fact, with or without these male chickens, hens would do just fine in laying as many eggs as possible. So when is rooster needed? In brief, roosters have nothing to do with egg production but have a lot to do in reproduction. 

Myths & Fasts You Must Know

As the facts may tell, roosters are necessary when the eggs laid by female chickens need to be fertilized into another chicken. But strictly speaking, again, roosters do not play any significant roles in egg productions. Considering a female chicken’s health conditions, it may lay a minimum of one egg per day, though there might be an alternating pattern every once in a while. However, there are cases when some hens cannot lay eggs due to some deformities in their genes. It is also possible if the hens are put into unfavorable conditions that trigger stress and other related illnesses. But most of these cases are caused by insufficient supplementary nutrients found in their diets. In any case, it would be better to seek veterinary help to rule out the possible causes. 

After the first six months of age, egg production can kickstart, though, during this time, the shells may not yet be in its fully firm stage. 

There is nothing wrong with the absence of roosters to fertilize the eggs. Some chicken farmers opt not to bring in roosters to their broods, especially if the target markets are for eggs and not for chicken production. Hens are genetically capable of producing high- quality, fit- for- consumption, healthy eggs. The only difference is that there would not be fertilized eggs that will continue the life cycle. And needless to say, they can serve protective purposes to their female counterparts regardless of the common fact that roosters can be hard to deal with and are troublesome at times. 

How Can Hens Produce Eggs Without Roaster

To understand how hens produce eggs naturally, let us consider the scientific aspects of egg production. Genetically, hens have two organs for reproduction: the ovary and the oviduct. One of these two ovaries does not serve its reproductive purpose and remains in an inactive state. For at least 24 hours, and up to 28 hours in the process of egg development which can take place at the healthier ovary. 

The process of fertilization can then take place afterwards. The yolk that contains the reproductive component can travel along the infundibulum (the part of the oviduct where the yolk is released into), where it meets with the sperm of the rooster. 

The process then continues as the fertilized egg makes its way into where the egg white or the albumin passes through the magnum where it can form and thicken for the next few hours. As the egg white continues to move along and gradually develops, the shells then begin to form in the isthmus for roughly two hours maximum. 

The almost- completed process will then rest to a halt in the uterus. /the egg will have to wait for 18 to 24 hours, enabling the parts to settle and the membranes o fully form. In the next process, the hens will finally lay its egg. 

The Varying Phases of the Egg Development Cycle

Chicks do not hatch as fast as can be imagined. In the same way, the freshness of the eggs is not directly influenced whether the eggs are fertilized or not. There are also no significant impacts as to the internal contents of the eggs, appearance, flavor, and other distinctive characteristics. 

The fertilization process continues in what is known as the brooding stage. This is the period where heat is crucial in deciding whether eggs hatches or not. In the absence of enough heat, the eggs cannot proceed to the hatching phase. Brooding can be done by natural means through hens sitting through their “broods’ to provide internal heat necessary for hatching. Or, this can also be induced artificially through the use of incubators where the eggs are exposed to controlled heat for at least 21 days. This is especially if hens do not incubate their eggs naturally to encourage the process. 

There is a process to determine whether fertilization has already taken place for eggs. In a process known as candling, it is easier to identify if eggs are fresh or fertilized. How is it done? Through light (candle for this matter, hence the term), the level of opacity of eggs is determined. As the light penetrates through the eggs’ membranes, spots, where embryonic stages have occurred, can be clearly observed. This can be done through exposure and practice, as not all eyes are trained enough for the purpose. 

Why Are Roosters Unnecessary in the Process For Hens To Lay Eggs? 

To reiterate the point, roosters are only necessary when it is needed to extend the process from laying eggs to hatching. Otherwise, the absence of roosters in the brood will not matter that much. Healthy conditions are the only determinants of successful egg production. Roosters, however, contribute to the fertilization process. For a period of 21 days, incubated eggs can turn into full-fledged chicks. 


Rooster-less Egg-laying: How to Effectively Encourage the Process

These are some important tips on encouraging higher egg production rates among hens, specifically for those female chickens that have reached their molting or are showing indefinite recess from the process. 

1) Ensure Nutritional Supplements Are Sufficient 

Ensure that the laying hens get the much-needed nutrients for their egg production as these greatly determines the success of the process. Additional supplementation can be necessary to boost the feeds available in the market even if these layer feeds are already packed with nutrients. 

2) Provide Safety From Farm Invaders

Keep watchful eyes towards preys lurking around the broods. One of the possible causes of stoppage in egg production is the predators that can be found in the farms. Rats, snakes, and other unwelcome animals can feed upon the produce, or can cause unnecessary stress to the hens. Some animals may feast upon these eggs, which could be why there are visible decreases in egg production outputs. 

3) Set Up Additional Lighting fixtures Inside The Coop

Proper lighting significantly affects egg production. When daylights are longer, the yields are also relatively higher. Thus, setting up additional light fixtures that can run for at least 17 hours per day can artificially simulate daylight conditions, enhancing female chickens’ performance.

4) Stage Comfortable Laying Spots

As with other reproducing creatures, when chickens feel that they are in a safe breeding grounds, they are relieved of stress and are more encouraged to lay eggs. Contrastingly, when there is no secure place to lay their eggs upon, chickens tend to randomly pick a spot, ideal or not. Or worst, they may not continue the supposed laying of eggs anymore due to stress and other related conditions. 

5) Do A General Cleaning Every Once An A While

Keep the laying grounds sanitized. The cleanliness of surroundings dramatically contributes to a reduced stress level among chickens. This means that it only takes a clean coop to encourage hens to lay more eggs or lay more frequently at a better quality. Perform a thorough cleaning, paying attention to all the corners where possible intruders and even pests can hide.
