Kizza,
For the plastic one, if you can make maybe two or three small holes (about the size of a wine bottle cork) in the lid and find some cork or foam material to plug the holes you can then adjust the ventilation as necessary while keeping the lid in place. Then perhaps you can get your temperatures up to at least 37.5 Celsius. That will also help you keep the humidity high enough during the least few days of the incubation period. Also with the holes you can use some rubber tubing to add water to the water tray without opening the incubator lid.
You are doing really great so far. You guys are really using your whits on this project and I think that you can be successful.
