Well heres the answer to my original question, NO i wont be doing that again, my 2 best birds came together(entered in the 2 bird race) but an hour behind the winners, But they looked o.k when they come, just needing a good drink when they arrived, trapped like bullets, got another 5 mins after. and waited another 20 mins then come away, At work this morning so i dont know if any more back yet. So i think it was just to much for them this time.
