well they started at about 830 this morning they each have a hole but the white membrane is still kind of covering it but the shell is cracked off should I help them?? or are they fine just leave them???? this is the first time we have done this and hubby had to leave for work for 2nd shift so I am all alone with them. how long does it usually take for them to start emerging from there shell?? any advice would be lovely. thank you.
