Dominant white canary
These canaries get their name because they have a dominant mutation, so it prevents partial sedimentation in their plumage of yellow pigments, so their appearance is white.
Recessive white canary
There are two kinds of recessive targets: English recessive white and German recessive white. This type of canary does not assimilate well the vitamins that produce the discoloration of the skin, fats and feathers, so it is important to supply vitamin A. Among other vitamins also important throughout life, and particularly during reproduction, moulting and abnormal situations.
The Tabernil Total vitamin supplement for recessive canaries is very complete in vitamins to give your canary.
