We have a big brooder in the livingroom that Farmer Lew built last weekend & it's pretty neat. Our house is very tiny, but it is just the 2 of us here so it's not so bad. That entire section of livingroom has been redesignated as a hobby area anyway a long time ago, as I do beadwork and jewelry design and various other small handicrafts, and DH draws, paints, designs, builds, etc.--we are just hobby-type folk. My beads have all been put away for the time being & the brooder and incubators have somewhat taken over. But as I said, it's just us & it's not so bad.
We are going to add viewing windows to the front of the brooder so that when our 2-year-old grandson comes over, he can watch the chicks without us having to lift him up and watch them from the top.
I think if we were more social people, had a nicer house, had carpet, or had more company, we would probably avoid brooding in the house. I am glad, though, that this next group will hatch the 2nd week of March & the weather will be better. I'd like to be able to put them outside in a grow-out pen by the middle of April--that'd be nice!
