On my balcony, my bikes are stored under a tarp. A pigeon has made a nest under there, between the bike tires. There were 2 eggs in the nest and 2 days ago I saw one hatchling. I'm not sure what happened to the other egg because over the past two days, whenever I've looked in on them, I only see the mamma sitting on the nest with no sign of either baby. Is this normal? My main question, however, is what can I do if I need to remove the bikes? I am moving in about 2 weeks and have to take them out. I can leave the tarp, but how much disturbance can a pigeon take? Any suggestions?!
