I haven't read all 7 pages here..... but...
we AI our cows and occassional pig. With teh poultry, though, I've never found a rooster worth breeding who couldn't rise to the occassionl. I usually give them 5-7 days in a pen together to flush the hen, then start collecting the eggs.
I'm not 100% sure, but I think chicken semen is like pig semen in that it cannot be frozen (like a cows can). This makes it a bit more complicated for timing's sake.
