I very rarely loose them Tractorboy but, I take it very slowly - as soon as they stop squeaking, when I handle them, I take them 1/4 mile then 1/2, then 1, then 5 then 15 in each direction after that I jump them out to 30. If the birds always fly south then, I suppose that the first time you release them from a different direction, they'll strike south and it will take them a while to orientate themselves. Mine have a surprise every time I let them go and they are used to it! ;D
