Feather plucking is one of the more distressing things a bird owner can watch happen, partly because it's rarely about one obvious cause — boredom, stress, skin irritation and underlying illness can all look identical from the outside.

Johnson's describe this as an effective aid to help prevent feather plucking and self-harm in birds, applied as a 100ml pump spray. It's positioned as an aid rather than a cure, which matters given how varied the underlying causes of plucking can be.

• 100ml pump spray
• Aimed at feather plucking and self-harm
• For birds

What it can't tell you. A spray cannot diagnose why a bird is plucking, and Johnson's make no claim to address a specific cause — if plucking is new, worsening, or the skin underneath looks sore or broken, that's a job for an avian vet, because treating the symptom while missing an underlying illness or husbandry problem will not fix it.

Who it's for: bird keepers dealing with feather plucking who want an aid to try alongside working out and addressing the underlying cause, not instead of it.
