I am sure if it was viable your set up would have produced results. It sounds like you did your homework. I've only incubator brooded with a cheap brooder once and quickly lost interest after discovering the ease of letting the hen do the job.
I only had 1 egg of 6 hatch...but I had little people helping at the time...and they knocked the incubtor over in excitement breaking 3 eggs and spilling the others.
Amazingly I caught one egg on reflex with the domed lid and it went waaa waaaa waaaa around in the lid until it settled. I still put it in with the last 2 unbroken. The hard spun egg was the only one that hatched.
I'm surprised the chick didn't stumble in a daze at hatching...it was spun so hard
Happy brooding
