It appears to help keep them in good feather.

I can tell that they are a lot more active and their feathers are much softer after starting to use this daily

I decided to try out this formula for him and in a couple of days, his feather appeared more healthy and he became much more active and chatty

We noticed that both of them have lusher feathers and the feathers are silkier and softer and shinier and stronger

His beak would cheap easily and his feather was not so shiny like before

I have been using it for several months now,and I've noticed that my Senegal parrots' feathers look noticeably shinier and more vibrant.

And his feather is shiny and grows back

Her feathers are growing back (mostly missing from her head and around her face)

I have noticed much softer and brighter feathers, and have been giving him this for about 4 months
