I'm quite new to raising ducklings and I noticed that duckling didn't start growing anything on two spots on its wings in 21 days now. They don't seem to be damaged or self pecked now, I did have a feeling they could be yesterday, but when I checked them today again it doesn't seem so - there are just bald spots. I guess they looked a bit damaged because of sun exposure. It loves to forage and it might have been in the sun a bit too long. Red tan has now disappeared. I assume that I'll have to wait for the first feathers to emerge on her wings before these to spots get covered.
