Yes, this is a slightly special situation. ;)
tbevans, if your air cell looks pretty close to normal now, I would go ahead and start lock-down to be safe. Keep us posted! ^-^
That's much better! I think you should be able to lock them down now, get the humidity back up. Be sure to lay them down with the lowest part of the dip laying on top. (in your pic, the floor should be on the side your hand is on, with the other side up)
Oh gosh, its impossible to guess. Today, tomorrow, the next day... hopefully by the weekend? Normally its within a couple days after raising the humidity, but this hasn't been the most normal hatch.
