had a white one down the chimney, did'nt know until it came back looking like a barless mealy, then one of my nabours told me she had to get the gas board in as there was a nios behind her fire, it was a pigeon they got it out and let it go, i did'nt tell her it was one of mine, the bird will eventually get down to the bottom, what about the rspca, they should do something,
