Of the styrofoam incubators, I have found the Hova-Bator to be better than the LG. It holds temp and humidity more evenly/consistently than the LG. It isn't a huge difference but it is real. I've run the two different units side-by-side in hatching at home and in the schools that I do the classes in.
I love my Brinsea, I have the octagon 20 Eco, I didn't get the bells and whistles but I tried one of those Styrofoam ones and gave it away,with the promise of a trade in the spring I didn't have any luck with it, I'm sure it was just me, but I couldn't get the humidity/temp right
I'm looking at this one (1588 Hova-bator Incubator PLUS 1611 Automatic Egg Turner) that hold 41 eggs for $169.99
And this one (Brinsea Octagon 20 Advance) that hold 24 eggs at $359.99.
I've read good reviews on both and prefer to spend for the Hova-bator but not if there is a huge difference in performance.
My 20 hens are laying between 14-19 eggs/day and I think now would be a good time for me to start trying to hatch some chicks.
Please give me the pros and cons of each as I would rather hear from you folks that actually do this.
