a few of my RIR eggs pipped end of last week, but they weren't doing anything else. I got so worried 2 days later, that I helped the pipped ones break the shells and the shells and the membranes were very tough. With the last 2 eggs, there were no pips at all, so I gently cracked each one. One was dead in the shell, but I could hear the other one cheeping, so I helped it out, and it was fine, but I think it was too weak and it died over night. But with some yoghurt mixed in with soggy crumb, it ate well yesterday and was running around with the other 5! Found it this morning. awwww
