Saffi and River have both had whole pigeons in the last week, and my lot between them have over the years eaten rabbits, fish, cuttlefish, pheasant, bits of deer, squirrels, bits of hedgehog, mice, doves, blackbirds, sparrows, starlings, so on and so on!
Never had any trouble except for Saffi, who's overenthusiasm at the prospect of something edible did lead to a few birds coming straight back up with a squeak (from her, I think she just got poked with a feather somewhere) but she seems to have got the hang of it now.
