I am convinced there is something wrong with the design of the two big bators. The smaller ones has proven to be okay.
Being convinced and all, I surced the net today and tonight, looking at pics of other peoples incubators. This is what I have decided to do. Please tell me what you all think of my new (improved) plans..
I am going to put in more lights, spaced closer together, in the hope that the tempreture swing will be less.
I am going to line all the walls out with heavy duty foil, hoping to cut out on any cold spots. I don't know what side must be showing.. The shiny side or matte side?
I am going to place a fan in. On the breath of it. I just cant figure if I should put them above or under the lights.. Or maybe between the eggs and water?
Then in a effort to keep the temperature as stable as humanly possible, I want to place a water thermostat in the water tray, under the eggs. It will be great for humidity and I think keep the temperature more stable..
What do you people think? Have I eventually lost my mind or am I on to a better thing here?
Any thoughts or comments will be greatly appreciated

. I want to built the best bator humanly possible.
