Sparrowhawk problems - Eagle owl tape anybody

[REDCHEQHEN]

Lost 2 hens and had further attacks, youngsters have only been out once, on Sunday and hens were attacked later in the day on return from a dreadful training toss where I think they were hit en route as well. 

I used to have an Owl CD but can't find it. Can anybody help?

Sadly constant strikes from birds of prey, both around the loft and on training flights, is the main reason I gave up the sport.
