A smart roos will call the attention of the predator, then lure it in the other direction, and hopefully fly off into a tree. If he's fast enough. You will know if you had a good roos when the hens come back and he didn't. Unfortunately it can take awhile for the next roos to replace him. Either way, a roo is no match for, say, a bobcat. As for the mating ritual comparison of bringing candy...I don't know how that would work...I can make candy, better be expensive jewelry. Ha ha. In a wild stage the hens will choose the roo, whoever is left standing, if she doesn't like him, she leaves. Now, it's up to you to decide if she can leave his sorry butt behind. Two words...crock pot.
