I was watching the eggs last night (it was the middle of the 19th day) and I saw at least half of them moving over the course of an hour. Once I heard a tapping and I thought maybe one was pipping but it didn't. The egg moved more after that but this morning I didn't see it moving but I didn't spend a whole lot of time watching this morning--I saw maybe only 2 move this morning in the short time I watched. Do the eggs do that? Move a whole bunch for a while and then be still for a while? (Before pipping?) I'm just a little paranoid that they weren't able to peck out of the shell.
some move, some don't. there is not anything set in stone about this. some don't seem to even be pipping and then, POOF, one is hatched out. no paranoia allowed. shoes of peace on your feet today!
