I'm sorry, Bloom, but I have no idea. I was feeling proud of myself that I was tech savvy enough to set it up.
The one in front seems to not have pipped enough, and looks like it's trying to HULK SMASH its' way out. Is this unusual?
The one in back made a good 1/2" progress while I was picking up my dd from orchestra.
AND, while I was gone, the one between the two with obvious progress PIPPED!! That means I have five who have pipped now.
Edited to add: I moved the incubator around because I think that other one is about to hatch, and will go first. With the new angle, I see that a 6th chick has pipped!!
The only one not to pip, I heard chirping from inside her shell yesterday.
