It happens to the best of us Twist. Good luck with your new chicks tomorrow, looking forward to the pictures. I think you need to invest in a tranquilizer gun & just get it over with, with the yaks. It's too scary with how large they are & you having not raised them their whole life. One bad move and you or someone else could be maimed or killed. We would all feel better here at grannys house if you just put them to sleep for a bit, then pulled the hairs you need for the DNA tests.
