Eggs in small packs bearing the words 'Deep litter eggs' must be produced in poultry enterprises in which:
- the maximum stocking density is not greater than seven hens per square metre of floor space available to the hens,
- at least a third of this floor area is covered with a litter material such as straw, wood shavings, sand or turf,
- a sufficiently large part of the floor area available to the hens is used for the collection of bird droppings.
