I have the same pipper that is mostly zipped, but not out, breathing fine and one low pipper. No movement from the other 4 eggs. Both the pippers are ILove eggs... Once my flock is established, think I'm done... unless it's to buy live birds from someone I know. I am almost sure I have a total of 6/8 roos from my eggs and possibly 2 BLRW roos... meh...
