Good house design
- ship lap timber
- simple
- great ventilation – long narrow strips of mesh protected as well as through the corrugations of the roof for bigger houses
- high ventilation – not around the heads of the birds
Bad house design
- plastic, tin,
- felt roofing – which attracts and promotes red mite infestations
- slats in the floor as roosting bars – very unnatural, and causes breast bone issues
- no perches – chickens want to roost from only a few days and weeks old.
