Monitoring hatching-eggs quality directly influences chick quality in the hatcheries and consequently a good start in farms. It is well known that healthy chicks come from good quality hatching eggs, and those healthy chicks will perform better. Therefore, every egg counts.

When discussing the production of hatching-eggs, many parameters are influenced by genetics, for example the number of eggs per hen, egg size, shell quality, and albumen to yolk ratio. Feed composition and feed restriction management at breeder farms are also key factors affecting hatching-eggs production. 

A continuous monitoring hatching-eggs classification is essential

In order  to improve the hatchery performance through the monitoring of hatching-eggs classification from the breeder farms, a clear monitoring plan needs to be set.
The plan must set clear objectives, design actions and responsibilities for each action. A key aspect is to have a system in place to monitor whether each objective has been met.

A case in Europe: Main objectives and indicators need to commonly defined

To illustrate this with an example, the following plan was implemented by a poultry producer in Europe having the monthly support of Ceva’s in ovo C.H.I.C.K. Program services linked to the Egg inject in ovo system. In this way, the percentage of dirty and very dirty eggs was systematically observed on arrival at the hatchery over four years.
 
The different evaluations helped identify what types of eggs were consistent with the standard, prioritizing discarding the very dirty eggs, and establishing rewards according to achievements. Results showed that the prevalence of very dirty eggs decreased by approximately 1.5% in the first year and almost 2.5% over the total four years. 

Considering that very dirty eggs are highly susceptible to generating rotten eggs and reducing hatchery hygiene and performance, the improvement plan contributed to the hatchery performance as it maximizes the number of quality eggs entering the setters, which is of particular importance when an antibiotic-free policy is in place. 

Therefore, the control of the percentage of dirty and very dirty eggs on arrival at the hatchery is paramount.
