I'm hoping to get some suggestions for a 24 (duck) max capacity (maybe less?) incubator that can work well in a house without central air? I try to keep the temp as stable as possible, but when we have outdoor temp swings from 30-70, it's not unusual to have fluctuations of up to 10 degrees inside the house. I'm not planning on hatching a whole lot, so was hoping to stay in the ~$150 or less range. This would be my first hatch and I plan on turning by hand. Also open to making my own, although I am a little worried about keeping humidity and temp stable in something homemade. Really appreciate any suggestions you all may have. I have read through threads and looked at reviews, but I wanted to ask about house temp fluctuations specifically as I would be devastated if I rushed into this and messed up a hatch.
