Quote:As I posted there, once a month I put avia charge in their water for a week. It's more preventative than needed in my opinion - I have never had a health issue with my inside birds. Once a month for a week they also get ACV in the water. ACV - apple cider vinegar Just a natural health supplement. Avia Charge was recommended to me about 3 years ago by several people on BYC. I use it on my outdoor flock of layers and for my Seramas. It is expensive but lasts a long time. All of my indoor birds also have lots of natural light through windows and lights on all their cages.
