We live in an apartment building in NY and our building's balconies are all under construction. The construction was paused in november, and resumed in beginning of April, today I opened the door of the balcony which wasnt opened for a long time and I found a nest with two eggs and a pigeon. The pigeon is mot flying away, they are right under the door, also behind the broken pieces of concrete that have piled up. What should I do? I want to help the piegons to the best of my abilities. Please give me suggestions. Thanks!
