I’ve always heard the same. If her nest is distroyed she will nest again and i’ve heard until it reaches a point thats too late in the spring after many attempts. This is probably why we see late hatch roosters that have minimum tailfeathers that are hard to decide weather to shoot or not. About nesting two or three times, i doubt it because if her first nest is succesful she protecting and teaching those chicks what to eat and how to fend for themselves. To busy to nest again.
