Have any suggestions about which is the best way to do that? If my birds keep at it then next winter I'll have to buy them fur coats.Feather plucking can be come habit, a bad habit. The one who looks the best is usually the worst offender. After all why should she pluck her own when there are others feathers to pluck and eat. They are usually a high ranking bird, so shaking up the pecking order may help.
