DO IT! Seriously, get the bator! I got one this past Spring (an LG, traded some hatching eggs for it- SCORE) and I've had sooooo much fun with it. No facility for humidity measurement means it doesn't come with a hygrometer, but you can find them at Walmart and just about any pet store that sells reptile supplies, I don't even use a hygrometer and I still get good hatches. You should go and read through the Incubating and Hatching Eggs section, in fact, its very possible the Brisnea has its own thread there. BEWARE- once you get your bator you'll discover you have a very addictive personality. Its a terrible, TERRIBLE disease! Good luck!

P.S- I'm setting some Silkie eggs today
