Natural light and outdoor movement directly raise Vitamin D3 levels, improve laying regularity, and support flock welfare scores.
3 Studies
Hens with regular outdoor exposure produced eggs with significantly higher Vitamin D3 concentrations compared to indoor-only hens.
Open run access reduced stress behaviours and improved laying regularity and overall flock welfare scores significantly over study period.
Natural photoperiod synchronisation improved laying consistency and egg quality metrics over 12-month controlled trials on commercial farms.
