Had my young birds out just there and it only took fifteen minutes for them to fly to the roof and start picking at the gutters so i just shouted them down for there feed not sure if i should have just left them up there because they really havent started flying at all yet and out of the nine that i have 3 dont even come out the loft but the other 6 are straight out could this be anything to do with they came from a different loft and a bit later on than the others
