Hi Jimmie, and welcome to Permies.
The stuff online is great but you're right, it's great to get some hands-on learning. I'm not close but hopefully someone who is can help you get your hands dirty. If you can't find someone, you could stop in somewhere they
sell eggs and ask if they can get you a spent hen at some time and maybe dispatch her for you. Then you could take it home and have a no-stress practice session. No worries if you mess up.
