If their nest has been damaged it can be repaired. Look for a shallow depression lined with grass/fur. Place babies in the nest with light layers of grass to hide them. Leave the area, or the mother won’t return. (Mothers return only at dawn & dusk.) If you find healthy bunnies that are 4-5 inches long, able to hop, with eyes open and ears up, they do not need help. They are able to survive on their own. Leave them alone. Questions? Call a wildlife rehabilitator.
