I have found that home processing is not difficult, but it is time consuming. Expect 45 minutes to an hour PER CHICKEN. The final pin feather removal can make it take even longer. Personally I much prefer using a processor, as the chickens come out looking MUCH BETTER than if we did them at home, and the cost is not the issue. I don't mind paying to have it done right, and the place we use is only $3 per chicken. They are also done much faster at the processor.
I'm glad you are feeling better today, and I hope you have a nice homegrown chicken celebration. How are you going to prepare it? One thing to remember, your homegrown chickens are not injected with salt solutions, so brining can help bring out a flavor you are more familiar with, if that is a concern.
