thanks!. its not badly priced either!. i just need a simple incubator that will hatch my chicken eggs and possibly be used to hatch silkworm eggs in the future. would the one with the fan be better for this?. the one i have from fleet farm is made of styrofoam and is still air model and as i have said i have had HUGE problems getting it to hold the proper temp and with baby chicks getting stuck in the eggs then i have to genly blott them with warm water to help them get out and its a huge pain to have to make all those little leg braces for them because thier legs are all messed up due to the instability of the incubator
