Neither Cetawin nor I would tell you that all rooster stories would turn out so well. We know the odds are against it. So far, I've been very fortunate not to have had a predator loss in the going-on six years of having poultry, but my number will be up one day. I do free range my separate groups alternately, each with its own rooster on duty.
Your rooster is your first line of defense; that is his job, why most of us have them. Odds are he will most likely lose his life, no matter how valiantly he fights, especially against a large predator such as a coyote or fox. If Cetawin hadn't been alert with firearm in hand that day, we would probably be eulogizing Lancelot. That doesn't take away from the amazing way he handled the situation, the obvious thought process he went through, the decisions he made when the lives of his girls were in danger. We still marvel at why he didn't just stand where he was, stock still, and hope the coyote left, but drew her far away from where the flock was hiding, didn't hide himself, but decided to deal with her in his own way. That showed something was going on in his brain, that a true decision was made. I've always said that chickens are not as stupid as some people seem to think they are. Gosh, I wish we could ask him if losing Hera to that same yote a couple of weeks prior played into his decision to fight rather than hide.
My own Isaac has always tried to get the girls to safety first and hasn't had to use his fighting skills (well, he likes to fight with Suede at the fence, the doofus) to protect the flock. I would expect that to be the priority, to push them to safety and to keep himself safe as well, unless he was forced to fight. I still don't know what he would do if a predator had one of his girls down and he was able to get to her, may never know; of course, the best situation is for him to never be put in that situation.
