tumblers dont come back

hi all
i have had my pair of tumblers for 7 months, let them out to fly today and they went back to where i got them from. the first time i let them out they had only been with me for 2 months and they flew back to the last owner. so got to go and get them again, as they keep going back to his lofts do i tell him to keep them? this is the only pair i have got, tried to get them to got to nest but they kept breaking the eggs. I have got the loft the man had them in so there home is familiar to them.
I dont want to keep them in the loft for the rest of there lives as they were use to flying daily.
If anyone has any sollutions that would great
thanx mickie

try and buy a few babies mate then teach them to fly to your loft that will be the best way

birdy mate .i just keep them very very hungry and let them out for a few minutes each day within a fortnight they are settled but i must stress hunger is the way to do it you might find it a bit cruel but it will work . i feed mine wheat for settling

you could be right mate i wasnt thinking in terms of tumblers i was thinking or race birds
