Now the builders have left I cleaned all the paths, patios etc., but now everywhere  is covered  in pigeon c**p.  How do I  get rid of them?

Is there a food source that is attracting them?  We used to have a terrible problem with them as we have chickens and they came for their food, but we have now netted over the top of the chicken area and they are gone, just the odd passing one now.

I think it's the pool attracting them.
