My girls have all gone through their first adult molt, and I've noticed that all of them have some fault bars in their feathers. I'm guessing that this is something that people who show birds know a bit about, since fault bars (also called stress bars) can increase the likelihood of feathers wearing and breaking. Does anyone have any particular advice on how to help birds grow strong, healthy feathers? Next year I plan to boost their protein intake starting in August, and perhaps add a daily vitamin supplement as well. Anyone else have any tricks for pretty feathers? Thx!
