Keeper tips for this variant
Feather-extreme breeds need help: hooded Jacobins have obscured vision (place food/water where they can find it and clip the hood for breeding), and the muffed/curled feet of many fancies must be kept on clean dry litter to avoid foot damage — these are aviary-only birds, not free-flyers.
