Birdfeeders - how many and how often do you refill?

Only if the lamb or Ewe is sick or not very well and the same for birds of prey and fox's even then the animal would be dead or on it's very last legs because they go for it or they are very very hungry

But you must not get mix up with a crow or magpie on the backs of Ewe's/lamb's when they are siting down, they're finding bug's or even maggots in the fleece to eat
