My new cockerel has been kept in my coop and run with the hens for 3 months. He is only starting to be accepted now but, he will not let me handle him and when I do, it gets ugly. I regularly free-range my other hens but, I have not let him out yet, last time I did he ran away for the whole weekend (this was in October and he came back.) Should I let him out or hold off until he's fully part of the flock?
