i had a pigeon nest on my balcony my boyfriend and i were really excited about the 2 eggs we saw it was a really beautiful nest and two beautiful pigeons. today i looked outside and the nest is abandoned and there is one broken egg left. im worried a neighbour has a small space under the divider of our balcony that she couldve gotten at the nest or maybe a crow? anyway i dont know what happened i dont know if the babies were born and are hiding, i dont hear anything but should i sweep up the nest so that we dont get more pigeons that lay eggs and get destroyed or should i wait to see that the babies arent hiding behind or in the couch that is near the nest. im so upset about this but at the same time i dont want new pigeons to come and reuse our space if not neccessary (we didnt notice the nest until after the eggs were there) some advice on what to do or look for... if its safe to remove the nest or not. thank you.
