cowboysgirlfriend, rooster wars are not fun, trust me, I know.
I would try to find some way to coax that boy out of the crawl space if you can. Maybe a special treat that he likes. You sure don't want him to die down there.
Just to show how 'nutz' roosters can be. I made the mistake of going into the coop two days ago wearing a pair of pink slide sandals. Usually a no no but frankly, I was tired, needed to gather eggs and forgot to change shoes. Chester freaked when he saw them. He pecked them, hitting my toes naturally (and making me dance) growled and then went postal. I held him off with my ice cream pail and finally got close enough to him that I clouted him a good one and told him to stop it NOW! Luckily that was all it took because he immediately snapped out of it and walked away as if saying to himself "oh, it's you. Okay, but ditch the pink sandals next time or it isn't going to be pretty!."
I was just glad that I hadn't gathered the eggs yet because that stinker trashed the pail.
