Welfare of organic laying hens kept at different indoor stocking densities in a multi-tier aviary system. II: live weight, health measures and perching

Multi-tier aviary systems, where conveyor belts below the tiers remove the manure at regular intervals, are becoming more common in organic egg production.The area on the tiers can be included in the net area available to PLAYSUIT the hens (also referred to as usable area) when calculating maximum indoor stocking densities in organic systems within
