I don't know how many birds were in the convoy and going with some of the post there are some big fat perigans out there if bigda's stats are anything to go by 65percent of 1000 is 650 that's a lot of perigans on the west route we are missing 7 of 58 that's a sad loss of approx 5 percent that's down to bad management ,bad weather,perigans,doo's not being right , wrong doo's for the day the list goes on so don't blame the west route perigans the birds have been getting slaughtered up the east for fn years.imo.
