Some of mine run when the alarm goes off, but some stop and look up. I actually think the older ones know that they should find the hawk before deciding which way to run. I don't think they even have to run from a Red Tail, just step to the side, like a charging bull that can't change directions. The smaller Coopers Hawk is a whole 'nother story!I only handle mine off the roost too. I've yet to see one of mine duck and freeze when a hawk goes overhead...they are too busy running for cover where they will then freeze. I've never seen one freeze out in the open.
I am interested in how people handle their birds, off the roost is the only way I can get my hands on them. I am not going to keep small groups or individual cocks in a pen, except for breeding or maybe a grow out pen. That means the cock has to come back to the flock after being in the breeding or grow out pen. I have never reintroduced a cock to a flock. I see conflict issues here.
During breeding season, I could hold back the best cock, send others to the breeding pen, and then not let them come back (cull) to the flock. Send the cock I held back to the pen next year and hold back the best cockerel from the pervious year. I know that is not how you should do it, but it might be the best I can do. In terms of a grow out pen, obviously the chosen one/few must come back to the flock. The longer you keep them out of the flock and the older they get the more issues you probably have with reintroduction. However, the longer you keep the cockerels, the better you can evaluate and choose a breeder. I knew this would not be easy.
