If it was to happen it would be fantastic, funding to set it up should and could come from the RPRA/Blackpool etc but the running of it should be totaly independent of the RPRA.
Best solution to me would be groups of say 10 bungalows with a warden and able bodied fancier at each location. One loft at each location run buy the able bodied fancier but open for the pensioners to participate and assist. This way they would be able to get enjoyment from the birds without the worry of being able to or having to care for them etc.
