I'm sure others can help you more, since I'm pretty new to it too. But I am fortunate to have a buddy who has called in a bird for me in each of the past two years. Last year, I shot one at right around 40 yards as he turned to leave, and he was still alive for a while. My buddy stepped on his neck until it succumbed, which seems like a good way to do it, since the bird didn't flail at him and he wasn't holding it where he could get injured. Having said that, I went and got it and brought it back the 40 some odd yards before he finished it off, and it didn't do anything to me either.

As for cleaning, I plucked the chest feathers and breasted it out, cutting the skin, pulling on the breast meat and cutting where it stopped. I'm sure others in here can elaborate on that more for you.
