Weighing broiler breeders during egg laying – stress-free!

Technology in the nest: the integrated scale determines the hens’ weight automatically every time they visit the nest.

Big Dutchman introduces Nesca 2.0, a currently unique solution for broiler breeder managers: the nest-integrated scale determines the females’ weight automatically, every time they visit the nest to lay eggs. Touching or interrupting the hens is not necessary. The result: an extensive data overview and weight determination without stress for both humans and birds. Big Dutchman developed Nesca 2.0 specifically for the Relax nest. 

Nesca 2.0 takes several hundred individual measurements every day. These data provide an extremely accurate picture of weight development, flock uniformity and bird health: a real improvement on the usual manual sample taken once a week. The innovation enables poultry producers to monitor weight developments exactly, to take well-founded decisions regarding feed adjustments and to reduce the workload while still enhancing welfare. 

Control via touchscreen: weighing processes can be controlled individually and intuitively with the Viper system.

The scale is controlled by the ViperTouch management system, a true Big Dutchman classic. The versatile computer offers poultry producers many attractive features, including controlling the time at which weights are recorded and configuring user-specific settings. 

Of course, not just new buildings can be equipped with this system. Nesca 2.0 can also easily be integrated into existing houses with the Relax-Nest. 


  • significantly reduced workload for broiler breeder managers because there are virtually no manual weighing tasks left, saving time and labour costs;

  • early reaction to weight fluctuations: due to the high data frequency, management measures (e.g. feed adjustments) can be quickly implemented;

  • customised weighing periods so the Viper computer can limit the weighing time to e.g. the morning before feeding starts, for even more accurate results;

  • option for a combination with other Viper functions: the weighing data can be viewed in the overall context of the house and be linked to other parameters, such as feed consumption and the house climate.
