Having more of a clue as to the "correct"(?) way to incubate, why wouldn't you?
I don't mean anything by it, I'm just curious. I'm sure your first time was strictly an experiment, but if you seriously want to start hatching eggs (taking the time to set everything up, the electricity $$$, etc.), wouldn't you want the best chance at success the first time around? If it doesn't work for you, go back to what does. Trial & error as you have said, right?
I personally know that Jim is the absolute hatch master, hatching out umpteen different types of birds, hundreds of them per year. So if he has an opinion about incubating/hatching, I'm going to follow his instructions to the letter. But then again, that is just my opinion. I do know for a fact that every time I have e-mailed Jim with a question, he has been correct in his advice every time. But you have to do what you feel is the right thing.
Weren't there some people looking for SLW?
