I posted on this earlier today on another bator post. I have a LG with fan added, Hova Bator with fan added..see the theme here my stores don't carry the fan already installed but it's rather easy to install..here are the instructions
Hand to DH with a screwdriver and say "install it please"
has worked every time for me.
I also have a Genesis..the Hova Bator for the simple minded.It's preset so you add the water and turner and life is less complicated.
My opinions I have all 3 running right now
LG-not bad slow to get up to temp if it falls holds humidity OK I won't buy another but nothing wrong with it overall.I have had the worst early losses from this one as it turns out but with shipped eggs I'm not jumping to the bator as the problem...tip toeing not jumping .
Hova Bator-temps will adjust quickly if needed..you have to play with it like the LG until you find the right temp. Holds humidity well.I do like this one and have been using it for the incubation process...I stager hatch so I move them out on day 18 to hatch.Have lost very few in the early stages.
Genesis-BEST by far gets up to temp in a mater of minutes.Holds humidity real well and the big picture window makes watching the hatching fun(we homeschool) I put 7 eggs in on day 18 to hatch this week..all candled well and all 7 babies have been born alive
Now for the cabinet incubators I DON'T recommend them at all...200 eggs every 21 days that's A LOT of chickens for those of us that have NO self control
