not good, but you never seemed to get hawk attacking the first batch did you ? No , so think about it, you then start to let batches of 12 out one after another.... well the first batch you released was as good an invite as any to come over and see whats on the menu... you invited the hawk to come, should have let them all go together and then you would not have seen a hawk at all. its a shame mate, but a lesson learned i guess.
oh happy days
