I have cuckoo marans eggs under a broody. Yesterday was day 21 and still no pips. Today, I lifted her and picked up each egg to inspect for any signs of pipping. On some of them, I could feel something "roll" to the other side of the egg. Does this mean the chick is dead? Should I remove them from her or is there any chance some will hatch out on today (Day 22) or later? Thanks!
