Yesterday and today I let my birds out to loft fly. In the flock is one of my cock birds that I just put there from the breeder section. He has raised two rounds and the last two young are in with the other young birds. I let him out with the others and he would fly around for about five min. and then land on the loft. He has done it yesterday and today. The other birds stay gone for about 30 to 40 min. He used to be one of those that would fly with the others and return with them. Could it be because he has put some weight on from having feed 24/7 for the babys and he is just out of shape?
