Elorraine52: Regarding incubating in a house with wood heat. I did it successfully last spring by putting the incubator in a room distant from the wood stove. I tucked it at the back of my kitchen counter, so it had walls on 2 sides, kept a bunch of towels handy to wrap it in at night when the temp. dropped. I did pay a bit more attention to the wood stove, but it was only for 3 weeks.
Re: water wigglers and feather dusters: Not every Walmart is equally blessed. I turned the store upside down in my area looking for both. My poor husband. He was following me through the store while I looked for feather dusters, when I didn't find one, I said, well, let's go look for a feather boa instead. Now, he thought either I'd totally taken a turn around the bend toward crazyville... or his evening was going to get pretty interesting! When I explained my purpose, he just shook his head, gave me the "look" and said "Uh-huh, that figures!"
So, instead of using a feather duster or a boa for a fake hen in the brooder, I'm thinking of using a bunch of polar fleece strips, loosely fashioned into a hanging chicken belly. Given the winter that we've had, I think the fleece would be more appropriate!
The last time I checked, incubator warehouse had bimetal thermostat kits for around $16.
I had a similar experience when mine picked me up from the store yesterday. I had a heating pad, feather boa, meat thermometers, dirt, and water ballons. I also had 3 easter baskets. He gave me a questioning look so I said "For the chickens." He just shook his head and said "I shoulda known."
