Rats like alot of them or just a few in their natural habitat?I'd say leave the gosling mama and papa are pretty good at defending their goslings from anything except a larger predator like mink or weasel or Snapping turtles. Or of course the really large preds. You have them in secure housing right?I have a goose bout ready to hatch some eggs and my options are to... Take half the goslings-leave them all-take them all- would the geese protect them from rats or not
