Help! I've had a pair of pigeons set up camp in the corner of my balcony. I noticed them snooping around a few weeks ago, but they've since built a "nest" (a few scraps of straw) and now there's two eggs in it. Can anyone had baby pigeons on their balcony tell me how much of a mess they'll make? I need to decide now whether to block access to the nest (it's behind my recycling bin) and let the eggs die (still cold at night) or to leave them alone.
Any advice appreciated,
