The mom is alive but just lays with the eggs. We have seen the male go in the vent (we assume to feed her) but we can’t have the nest in the vent. I don’t know if there is a place that I can take them for a rescue, or what to feed her….. I just don’t want to let them die.
In Oregon it is legal to remove the nests of house sparrows, by the way. And I know how to secure it after they are out- that is not my question.
