I'm a newb at this, so here's what I got. 
It's a medium sized box. 25 inches width, 10 inches high. On the top, in this picture, you can see a wool blanket over some screen on the top. The screen panel has small holes, and I guess the wool blanket has been insulating inside, cause' I stuck my hand inside (Don't worry, there are no eggs inside besides some grocery eggs to see if they would heat up. They feel like warm, toasty rocks LOL) anyway I put my hand in and it felt nice and humid. The air feels warm. Not "hot". Soon I'm going to put the wool blanket or some tin foil around the insides to get some more insulation. I know. It's ghetto. Anyway, moving on. By the way, I've never incubated eggs, so I have NO CLUE as to what properly tempered (temperatured, whatever) eggs feel like to the hand, or what the air should feel like when I open the top. I have no clue as to if this will work. Any of you guys out there, gimme some tips! Please! These eggs will (hopefully) be the first of my flock. And yes, there's venilation/breathing holes. NEXT PICTURE.

Here's the inside! In the left hand corner is a bowl of water, about 2 inches deep. I think this is called "surface area" and helps with the humidity in the incubator. That light in the middle is a red 75 Watt Fluker's clamp lamp, designed to keep animals warm. Do I need more heat in there? I'm getting a thermometer and a hygrometer today, so I'll post what my results are. I think it's only in the 80's, if that. The insulation should help. Any ideas on how to turn up the heat? Or.. any.. ideas.. at all ... I'm taking all advice lol. And in the back (you can't see it in this picture. I apologize for the dim lighting) there's a 12v PC fan that wears out all the cold and hot spots and "pushes the air around", I guess. Wish me luck tomorrow (I won't begin incubating tomorrow if this thing doesn't get the right temp soon.
