I save the smaller apples and chop up for blackbirds. Only put them out in the morning so they've gone by night time.
I've taken to 'spiking' the apples onto adjacent shrubs/ bushes where the twigs are strong enough to bear the weight ( + bird!). The blackbirds, thrushes, jackdaws etc etc seem to adapt to the 'kebab' presentation and keep coming back for more - seems to beat the rodent problem from occuring, so far.....??
