Interesting point I noticed when letting the youngsters out and then calling them in for their feed shortly afterwards From Monday to Friday due to work they are let out at 1700 and fed in by 1745 and they trap as if they are starving. Then on a Saturday and Sunday due to not working I let them out at 1600 and they are poor to trap I know it might seem so simple but it just shows you how much of a creature of habit pigeons are, keep them regular and you have control lol
