Its been 36 hours since my eggs started internally pipping and there has been almost no progress since then. Yesterday the eggs were rocking like crazy and now today they are barely moving. Whats going on? Should I be worried. Someone had earlier mention that membranes could be dry, if this is the case is there anything I can do to correct it? Here is a picture of on the the eggs. This is the only one that has made any progress and it still hasnt broken through the shell.
