Not even just from your home to your neighbour's.....Not even room to room. Just by having your own climate control going can mess things up.
I got one of these incubators that are popular with people....I do not like it. I am nagging Mike to make me two more so I can sell the two I had to buy because of going on an egg spree. The temperature is flaky in the purchased incubator, fluctuating by at least a degree depending on if the AC is blowing or not. No, it is not in the direct line of the vent. I know that one degree fluctuation either way isn't a "big deal"...but, it's the fact that it even happens that's annoying me. I've not even bothered to keep the hygrometer in there because - let's face it - my humidity is in flux as well. Well, and I have no water in it, so.... So, screw it. I'll weigh them, keep an eye on them, do my best to keep the temp as steady as possible - and, otherwise just keep nagging Mike to make me a new incubator where I can keep my temperature within .2 degrees of my target without fail and can keep my humidity right where I want it, when I want it with a small twist of a knob.....Generally, it's "off"; but, when I need to bump it, I can. I have screwed up my hatches, me - not my incubator. And, I'm finding I'm more and more prone to preferring my ability to micromanage
if I want to. Sad to admit, isn't it?
I do have to admit to liking the automatic egg turner, though....trying to get him to build around those dimensions so I can keep it.
