This website is made to inspire breeder farmers, hatchery staff and broiler farmers to improve hatchability, chick quality and performance. A better understanding of the incubation process ultimately will lead to better care of the hatching eggs, higher hatchability and better chick quality. Even more important, paying attention to egg quality, any improvement in the incubation process and rearing conditions will pay out immediately. Hatchability.com serves as a bridge between incubation science and hatchery practise.

The best incubator??

You need the best team in the hatchery! Today there are no really bad single stage incubators on the market. It is far more important to invest in your hatchery staff to learn them how to work with your eggs and incubators to be able to hatch high numbers of good quality chicks. And to keep your customers happy. On this website you find the best information for free, selected for you after years of practical hatchery research. So much is written about egg incubation, but not so many papers can be used to improve production results. You can take the long route and look up everything yourself, or take the short route and wander through this website and train your staff yourself, or for example invite me to organise a HatchCheck, or for an on-site / on-line training at your place. A perfect opportunity for you to support your staff and help your customers as well with better chick quality, less troubles and higher profits!

Hatching egg production

hen1 A high number of fertile eggs is the result of a good rearing period. Uniformity in the development of organs and glands is by far more important than having a uniform body weight profile. This can only be achieved by a good understanding of breeding biology of males and females during rearing, and to provide the right type of feed and optimum circumstances during the specific phases in rearing. Overfeeding or under feeding may easily occur and have a huge impact on organ development and future peak and persistency in egg production. This picture and more information about this topic can be found in Schneider et al., 2005. The broiler breeder precision feeder project by Martin Zuidhof is very interesting and flock uniformity has never been so high. Check out his video!

High hatchability and good chick quality

But hatching eggs need to be fertile as well... Prerequisite for high numbers of fertile eggs is to get strong, viable embryos inside the eggs. The roosters need to like the ladies in the breeder house - and vice versa. Good mating between healthy and well developed attractive birds results in strong embryo's and a high number of fertile eggs. The egg content needs to support the embryo either during storage, but also during the first phase of incubation. Wonderful how Mother Nature takes care of this, and we can copy that! See the section embryo viability. computer chick The process of embryo development during incubation is nothing but a miracle... When these biological processes are supported by the optimum environmental conditions, a beautiful young chick will emerge out of the egg. When conditions do not meet the requirements of the embryo, it will have consequences for hatchability, chick quality and post hatch performance. Embryo temperature is the result of the balance between heat production and heat loss, and insight in the factors that affect embryo temperature can be of great help to avoid hatch loss and deteriorated chick quality. For the mathematicians under us; the effect of air temperature, egg weight loss, humidity and air velocity on embryo temperature can be calculated! Variation in air velocity inside the incubator reflects the variation in embryo temperature, which will have consequences for embryonic development, hatch time, hatchability and chick quality. See the section about embryo temperature

Offspring performance

When finally good quality chicks have hatched, it is of great importance to transport them gently to the broiler or rearing house. Again, all environmental conditions during transport and in the broiler or rearing house need to match the requirements that the young chicks have. Innovative rearing systems as Patio or Hatchbrood / Hatchcare aim to take care of the young chicks. Basic principles however are the same as in traditional broiler houses. See the section chick quality The incubation process and the first week broiler house conditions are of great influence on broiler performance. Growth, breast meat yield, feed conversion ratio, gut health, feet quality are all be improved by incubation conditions. To minimise broiler mortality, enterococ infections in femurs and bone marrow, E-coli infections and slaughter house condemnations, think of incubation quality and first week housing conditions first!

Incubation: costs or profits?

The incubation process plays a very important role when you want to optimise technical and financial results in your hatchery or in your poultry integration! Not only hatchability will be increased, also chick quality, chick survival, broiler growth, feed conversion AND slaughter yield will be better! This makes incubation not a cost center to your organisation, but a profit center. Each small improvement in incubation conditions will improve your technical and financial results, which may reach over millions €€€ per year. You can make your own calulations using the "cost & profits download" on the downloads page.

The examples below are calculated using the following assumptions:

The setting capacity of the hatchery is 1 million eggs per week. On average, hatchability is 85%, broiler mortality is 3,5%, body weight at 40d is 2,0 kg, feed conversion ratio is 1,6, and breast meat yield is 20,0%. It can be seen that small improvements in incubation conditions can yield large profits in the broiler value chain.
