As feathers consist of dead cells & are consequently not fed by the metabolism, they absorb the colour when they are formed. On average, the plumage is changed once a year. However not in one go. The moulting of the old feathers is stimulated by the formation of new ones & this is a gradual process so that the bird keeps a full plumage. When YEL-LUX is added to the food it is transported to the place where the feather grows & it takes on the more yellow colour. The feather grows & it takes on the more intense yellow colour. The feather formed retains its colour until the formation of a new feather. Use 1 level measure (=1g) per 100g of egg food. During the breeding season: Daily from 2 weeks before laying the first egg until after moulting. During moulting: Daily for the entire moulting period. Show birds: Daily for the entire show season.
