9 9 LOHMANN TIERZUCHT › MANAGEMENT GUIDE Modern aviary systems generally use nipple drinkers for both rearing and production. There are also other vari- ations of nipple systems each offer- ing their own solution available on the market. A 360° nipple is the pre- ferred option. It is worth considering that early feed training is easier to accomplish in a chain feeder. Matching the feed- ing system in rear with that in the laying house will ease the transition period allowing for optimum early uptake. While it is not always possible to have identical house furniture you should always think of how easy it will be for the hens to take to the new equipment. This is particularly the case for feeding and drinker systems.

Aviary systems Multitier aviary systems though sim- ilar in principle will often differ in design dependant on the manufac- turer. The systems themselves comprise of metal or plastic slats and carefully positioned drinkers and feeders, all designed to encourage movement and natural behaviour throughout the system. Early movement and feed train- ing are two important management strategies in these systems. Lighting is also very important with- in an aviary rearing system as this will play a vital role in encouraging birds to use all the levels effectively. There are many positives in adapting to alternative aviary rearing systems: › Many production facilities are al- ready converting to aviary to allow more birds per house footprint. › The systems are designed to encour- age natural movement behaviour › The design allows birds to perch, roost and explore! › Early training and movement can give the birds an optimum start in life. › Allowing the birds to explore from an early age encourages uptakes and strong healthy pullets. › Matching facilities eases stress during the transition period. › Ensure when moving chicks from tier to tier a portion of the chick paper is moved with them to as- sist in coccidial replication. Chicks should only be moved after the first replication (15–16 days).
