Poultry farm Siemons

Let’s have a look in the multi-tier house of Ad & Andy Siemons from Roosendaal, the Netherlands.

Ad Siemons started his poultry farm in 1978. He equipped his first aviary house in 1994, followed by a multi-tier house, equipped with aviary in 2005. He build the second 2-tier house in 2010. This house is equipped with the Jansen Poultry Equipment Comfort 2 aviary system.


The new house of 97 x 16 m is equipped, per tier, with the Jansen Poultry Equipment Comfort 2 aviary system with LayMaxx nests.  The Comfort 2 system is a multi-tier system,  where the living area for the birds in the house is enlarged.
It is carried out with one manure belt  above and one manure belt beneath the nests and a free height of 500 mm.
Every tier is provided with Twin-World slats. This slat combines best of two worlds in plastic and wire slats. That’s why the Twin-World slat has a lot of advantages. Like the open construction (no manure traps), strength, self restoring, easy to clean and not in the last place, insensible for blood lice. In the slat we integrated the egg gutter.

The LayMaxx is an automatic nest system for laying hens, where the optimal laying results can be achieved. The LayMaxx is available in sections of 2440 mm long and 480 mm deep, the egg belt will be 500 mm wide.
The LayMaxx is provided with a unique movable nest bottom and a roll-up back wall. When the nest is closed, the red flaps are rolled up, what makes it easy to clean the nest mats and also to inspect the nests.

The eggs are transported for the upper and lower level to the central egg room. This egg transport system is absolutely unique and needs little maintenance. With the FlexBelt all eggs are transported in a save and reliable way.

To dry the manure, a drying tunnel is placed next to the 2-tier house. The tunnel is 11 tiers high and approx. 20 m long.

Ad and Andy Siemons have gained in all the years they are keeping birds in aviary systems an awful lot of experience. At the farm of Ad and Andy Siemons are 100,000 laying hens kept in total.

Why did Ad & Andy Siemons choose for the Jansen Comfort 2 aviary system:

  • Every row has a continuous row with nests;
  • LayMaxx nest has an easy foldable bottom and another advantage is, the birds keep the mat clean, when the nest is closed;
  • A traditional aviary system with a solid construction;
  • A drying system which in practice has proven to work well.
