Ali mac is right, about five years ago i lost almost 100 poults to Gos in two weeks , (THE ULTIMATE KILLNG MACHINE) when it comes to Pheasants, the worst case scenario when it comes to Gos kills on poults is the stress on the birds that survive, not only did i lose roughly a hundread poults i had to treat them from cocidoses their after. I know now when i enter a pen if a Gos has been, you will not hardly see a bird and when you start looking they have the fear off death in them, i have even had to pull poults out of rabbit holes that have been trying to hide from the Gos.
