This Is A Good Product To Help Prevent The Birds, As A Deterrent, From The Initial Stages Noticed Of Picking On Each Other & Plucking Their Fathers Out. I Would Like To Also Say, That It's Best To Take Away The Bird/s From The Group, If It's Continually Being Picked On & Treat It On It's Own In A Separate Cage, Until It Has Fully Recovered From Loss Of Feathering & Safe To Join The Group Again In The Avery At A Later Stage When It's Fully Recovered - Thank You.

Excellent product
