Q: How long does it usually take a robin to build a nest? Are robins sometimes inept at nestbuilding? I have a robin who started a nest in my front porch light. It appears there is some dirt or mud in the shade and the raffia-type grasses hanging loose and stingy, with no structure, all around the outside of the shade.f you move a robin's nest the parents will most likely abandon the nest, eggs and/or young. Here's why: Nest-site fidelity grows during the nesting season. The more time and energy the birds invest in the nest, the less likely they are to abandon it when disturbed.
