In order to make it easier to add water to my Hova Bator 1588, I rotated the top so the air vent is closer to the water troughs' fill wells. I can now poke a plastic tube down through the air vent and over to the wells or sponge to add water without lifting the top or disturbing eggs. The plastic tube doesn't stay in the air vent - it's only used when adding water.
I had to make a new notch in the styrofoam top to accommodate the turner cord, and plugged up the original turner cord hole.
I ran the bator and kept records for two days before making any changes. Now two days after the modification, the humidity is still stable and everything seems to be working okay.
In the long run, will turning the top like this mess with the humidity or disrupt air flow or anything? Thanks!
