Thanks, i've got one of the hygrometers set up to test it! :)

also working thru all of the info in this post, i had cross posted to a couple of other threads to try to get more help. http://www.backyardchickens.com/t/1046313/incubating-w-friends-come-hatch-learn-chat-meet-new-friends/85680#post_16904424
