Maske, Rode Kleurstof Vloeistof, 500mlMASK is a red vegetable dye in Easyyem herbs containing natural extracts. It does not color directly on the feathers, but enhances the existing red color. Thanks to the natural carotenoid, MASKE plays an important role in creating a bright red color. It is suitable for all birds (goldfinch, canary, red mosaic,) that have red feathers. INSTRUCTIONS: 1 month after birth, daily during moulting and shedding, 10 ml in 1 liter of drinking water or 10 drops
