No doubt they've thought about all the options, I'm just interested to learn what they can and can't do, re teaching them. Like the predators in Australia that kept dying because of the poisonous Cane Toads that were introduced - they captured some predators, and let them feed on Cane Toad meat...
Simon, re poisonous food in the wild: can't you teach the orphans back at base which foods they should avoid, so that when they enter the wild they have a head start?
