Answer 2

Explanation:

1. As a general rule, birds won’t mate until once nest is ready hence bird will not find itself without a nest, but if some mishaps occurs like nest is damaged or destroyed, it will try to lay egg where it had built the nest
2. In case of rock pigeons I have seen that if the nest is broken, and if nest place is inaccessible, it does lay egg on flat surface, as once egg is generated bird cannot contain it inside body
3. Now, consider case of brood parasites like cuckoo, once it has distracted the victim or rather foster bird away from nest, it will have relatively less time to mate and then generate egg, so in this case brood parasite birds have sacks to store semen, and it will generate egg in that small time gap available :)
