Danny_57, 12/01/2011 11.51:Beautiful goose Ferro, in Flemish the "knobbelgans". When you want the "diluter" blue in your animals you have 2 possibillities : -you wait until the mutation happen from it self in your stock; -you buy an animal who have that mutation. Blue "Bl/bl+" is an intermediar coloration but it pass on to the offspring in a Dominant way. Is this what you intend?
