Just finished week 3 and I'm finding the course increasingly interesting.
The bit about males fighting over dominance has been useful. Having a cockerel and an older cock, there has been some fighting between my males as the younger one has matured. Previously I have intervened to prevent damage to the birds. The course showed though that one would back down, maybe run away and hide. He would also stop crowing. Once that new order has been established, the fighting stops or diminishes.
So last time there was a bust-up I let them get on with it, one chased the other all around the orchard, as in the video clip, then the cock submitted, stopped fighting and ran away.
Interestingly, the young cockerel now has all the hens in his harem, and the old boy is on his own. He spends his days sunbatheing with the sheep, or foraging amongst them. He spends the night in a separate house with some 12 week old pullets which are not going out much yet.
I have found the bits about aberrant behaviour interesting too, especially the fact that my free range hens show none of the problem behaviours at all
