Thanks all...
Yeah it is a bit pricey...I am leaning on going back to perlite...I may or may not give this hatchrite a try...As I said, I have always used perlite, but just got a bit discouraged this season with a poor hatch rate.
Buuuuut I am guessing that has more to do with the fact that my incubator, full of eggs, was unplugged for roughly 8 hours as I moved from Minnesota to Kansas over the summer...not so much the incubation medium.
I have contemplated doing this...I am just affraid of a hatchling get tangled in the diffuser and drowning themselves...I know it's unlikely, but after this season, I didn't want to rule anything out...
Oh well...I have a few months to contemplate all of this.
Thanks again all!
