Hi there, hope you are enjoying BYC!
What a worthy goal.
When I first started... we skinned the chicken due to all the horror stories I read about plucking stinking to high heaven or ripping the skin off type stuff. Eventually we wanted to be able to cook a bird with the skin on or at least quit wasting it in the trash... so I decided to try plucking. The one piece of equipment you need for plucking is a thermometer for your water temp. (at least the first couple times until learning what the water bubbles look like around 145-150F). Add some dish soap into the hot water to help minimize any smell. I was truly shocked at just how easy it was to pluck! After making sure to swirl the bird pull at the long wing feathers to check readiness. Easily removed, ready for plucking. Not very easy, dunk and swirl some more. Beyond that I just use a knife and cutting board. Oh, and a homemade cone from a vinegar (or bleach) jug for dispatching via the jugular. I have tied them up by their feet instead, but have more control with the cone. Some folks will use the broomstick method, wring the neck, or ax & stump I think are some of the more popular methods of dispatch in addition to the cone mentioned. I suggest watching some videos and seeing which MIGHT be the best for you to try.
I never do large batches as it's just me processing, so usually 2-3 birds is my max in a single day.
Raising heritage breeds... the skin really is not delicious, to me. I'm a bit of a texture freak. But my dogs love it. Come to find out, I'm not fond of the skin on younger birds either. Beekissed said she just left her offal for her animals to clean up. My dogs did enjoy the foot they got a hold of last time.
I used to drain and put offal in a double bagged garbage. But started leaving it on another part of my property for scavengers. No point in wasting my energy to bury what one will come behind and dig up. I did bury it the first time I tried, it got dug up and left for my own animals to find which they did.
I am slow (meticulous over thinker) and each bird takes me about half an hour - 45 minutes which is down from an hour and a half each when I first started.
I kennel all the boys I will be processing after they go to roost or before the sun comes ups. I don't offer feed or water that morning. And I don't have to chase anyone. Having been overnight without adding stuff in is SUPPOSED to help make less mess... no full crop and almost empty intestines make for more room to get my hand inside the cavity.
I did have a friend over helping do his birds when the plucker I bought suddenly stopped. The plucker never really gets it all anyways even if it is a tad faster, you still have to pluck some by hand. Never mind checking the GFI... I plucked my next birds by hand... it was almost easier than washing out the plucker. Surprisingly no big deal... as stated by another poster!
One nice thing about doing as few birds as I am is that I can air chill them in my fridge instead of an ice chest. I was also shocked at just how much longer the chicken stays fresh in the fridge. Up to 14 days with NO nasty smell or sliminess like market chickens. Rest the meat before freezing.
Also, you are correct... most folks willing to process for me were not willing to do less than 10 birds to be worth their time. But in addition to that, it was at their convenience... and sometimes there are accidents, attitude, or other reasons you may decide to process one sooner... then there ya go below 10 already.
Lots of good support and advice here. Good luck!
