Keeper tips for this variant
Many of these colours are recessive and have been line-bred, so source from a reputable breeder and outcross periodically to avoid inbreeding depression and reduced fertility; the birds themselves are no harder to keep, but maintaining a true-breeding colour line takes years and careful pedigrees.
