This is an unsolicited testimonial from Brian Bohl who has been using Tummyrite for Canaries since October 2015. In this video he showing how healthly the bird look and in particular the quality of the feathering. These birds are currently going through the moult but the feathering is developing very beautifully Tummyrite contains some key amino acids and good quality proteins designed specifically to assist with feather development and birds going through the moult. A very pleasing result. Thank you Brian for sharing this with us. Michael.
