Joel Salatin videos are pretty good. There was also one by a kid who had apprenticed at the Salatin farm who made a good video of the whole process.
I have seen a few which include the killing of the chicken--that is something you need to be familiar with.
We raised birds last year and sent them out to be processes. We only had to kill 2 ourselves. This year we are processing on farm. We did our first batch of 10 meaties plus 5 extra roosters. We use a cone and cut the carotids. It seems pretty non traumatic. The plucking was awful...I had bought the $76.00 drill plucker attachment and it was ok, but there was still so much to do by hand. It made it a much longer day than was necessary. We will be doing batches of 15 every other week or so....and after this 1st experience, we ordered a Yardbird plucker.
We use a Havalon knife with a changeable blade for killing and another brand of sharp knife for eviscerating (forget which brand). Sharp knives are vital.
Ice in a garbage can or large bucket for chilling the carcasses asap after processing. garbage can for throw away parts and bowl/s for the keep parts. Freezer bags if you are freezing.
Good luck!
