The Bolegg Terrace is a compact, but complete aviary system for layers which can be placed in adjacent rows in the house. Laying nests, perches, feeding and drinking lines and manure belts are integrated into the system. The special system design allows birds to move up easily. The system allows a higher bird density compared to normal floor housing. With the high quality integrated Vencomatic nests, floor eggs and second quality eggs are reduced to a minimum.
