And to the person who was asking whether scalding was necessary to pluck, no, it's not, but apparently it makes it a lot easier. We couldn't quite figure out the logistics of getting hot water outdoors - we don't have a propane campstove and I didn't want to use the good pot (which we use for making beer and cheese mainly) on an open fire, not to mention the difficulty regulating temp on a fire! So we decided to try it once without scalding. It worked ok, but it's really hard to get all the feathers. And it takes a lot of strength to pull out the wing feathers - I couldn't do it, actually, though DH could. So we'll probably scald next time.
Just a tip about how I do this, for those that are just doing a few in their backyard. I have a large stainless steel bucket but a canner or tamale pot from an ethnic grocery would work well too. I put it on my propane grill before I get started, giving it about half an hour. I check the temperature and when it gets to 140 degrees I turn the grill fire down to the low setting and start processing my first bird. My water seems to stay at the perfect temperature doing it this way, although I'm sure it takes more propane gas than I would care to use.
I can't use a wood fire here in the city and don't want to buy any sort of burner for the 25-30 chickens I process a year so for now this seems to be working. If I happen to see a single, electric burner like the kind used for canning for sale, cheap sometime I may buy it.
Anyway, just a little tip that works for me.
Another tip that works and saves a little money. Before processing, freeze a bunch of water filled gallon milk jugs. That way, you won't have to buy a bunch of expensive ice to chill your meat. I usually keep the birds in a cooler full of ice water in giant ziploc baggies for a day before freezing or cooking. I never have enough room in the refridgerator for more than one. If I do need to freeze right away for some reason, though, resting in the fridge after defrosting has worked just as well, if not better.
