Pigeon deterrent netting (Cv3 6jd)

Hi, I’m requesting netting of some kind that would be suitable for balconies. Old sports net maybe? Goal netting perhaps or even netted wire garden fence. It’s to stop pigeons nesting on balconies, not because I dislike them at all, it’s because it’s unsuitable for them, one pair survived, I cleaned off the balcony but then another 2 eggs were laid, one chick died about a month in, then the second pigeon died just as he was big enough to fly off, so I’m keen to not have this happen again, it’s not a healthy nesting place for them as the poop has no where to go.
