hi there, i trained my birds today from 20 miles and they took pretty much all day to come home. i am still 2 missing but thats not the problem. the problem is all my birds have been raced and have even got a few card winners, but for some reason they are not racing home. they are healthy and fit so im a bit lost. any ieas would be very welcome. forgot to say they have had 8 tosses before today.
