Bette - sparrowhawks take what they need, I haven't seen ours for months
As for foxes, well it's humans who pen chickens etc which are naturally roosting birds so Foxy Loxy has plenty to keep him/her busy. They cache any birds that are left over, digging them up when required. Not a pretty sight when the fox has been in the pen 'cos they kill or maime everything
........... and they are about in the day time as well as at dusk, particularly at this time of year. It's hedgehogs which are poorly when seen in the day light, not foxes which prowl all the while, we don't see them as much. A friend watched a fox digging under the wire fence, he took 3 days to make a small hole under which he slid towards her ducks, he caught one and pulled it back under the fence
......... apparently male urine weed round the plot keeps foxes away, however at this time of year

To protect free-ranging birds buy a couple of llamas
