I love timing the birds in by hand but sometimes feel its scaring the youngsters into racing home,i once had a good sootjen cock spoilt when my mate grabbed him wrong in the loft,one week he was 1st club 1st combine,then week after 1st club 2nd combine,the week he was grabbed he was 2nd club ,2nd combine.After that he was never the first pigeon and would never trap straight up.I agree with the e.t.s system.
