Hi, y'all! We have moved Blossom the duckling into a large guinea pig cage next to her cheeps in the smaller cage. They all spend their time huddled next to the bars being close to each other, but the chicks seem to be adjusting to the change better than the duckling. I am concerned that she does seem pretty low energy, and am thinking that I should add niacin to her diet. Where do I get it (we live in an urban area and 'duck supply stores' are fairly far between), and how do I add it? Thank you!
