Alterna Aviary Housing System for Layers

The Alterna aviary housing system features an intelligent design to achieve excellent egg quality and maximize the percentage of marketable eggs. Operating costs are low, because a second floor can be installed on top of the system. This gives farmers the ability to double headcounts using the same floor space, while remaining compliant with legal provisions. Capital outlay and labor costs are reduced.

Alterna - 3 widths available, also as Base or Plus version 

Alterna Base and Plus

The Alterna Plus system has larger sections, while the Alterna Base system has narrower sections. Base and Plus have the same properties and benefits as the Alterna system.
