On a good note my (borrowed) bater went down to 40% humidity this morning!! I've been in a mini freak out for a couple days!!
It had been at 50% for both days before eggs & the first day with them in (Sat), then extra water dripped in the pan when removing the lid- for fixing the eggs that don't roll right on the grid turner, some kinda want to to roll to the side. (Roll-X has a water bottle that kinda gushes when you pull it out/put it in slot to open lid).
It spiked to 65- 70%+ Sunday night, I pulled the water reserve for it drop & emptied the bottle out so it would let humitidy escape!!
I pulled the bottle so humidity could escape from it's hole (heat mantains temp fine) I got it to 60% Mon night, down to 50% yesterday afternoon after I put a fan in the room to blow air OUT, last night it was 45% . 50% is "the ideal" Jenny used to hatch with it, 90- 95%+ rate with fertile eggs!!
This morning I put the bottle back in the slot to stop drasic humidity dropping (empty of course!!) as it made it down to 40%. I'll just keep it about there for a week - maybe put it to 50% a few days before lock down & 60-70% jump!!
