Of course my trial runs before eggs went well but now I am day 19 should be on lockdown and I AM STRUGGLING!! I am using a small home made styrofoam ice chest that is about 8”x8”. The whole incubation time I was able to keep humidity between 40-45% with little effort. I have increased sponges and water etc for lockdown but cannot get humidity up above 50-69 at most. If I spray warm water in incubator through vent holes humidity rises but it is short lived and then temp drops to the mid 90s versus staying around 99-100. It is a still air incubator. I have even tried putting a bowl of water directly under the bulb with no increase. PLEASE HELP!!!!
