Ok I'm new to this. I have egg in my bator that are past due. 1 hatched sunday and 2 internally piped but didn't make it out. The others are still alive but I'm wondering how long I should wait before trying something else.
I don't mean to sound flip, but I would wait until they hatch
You may think they're due but they may have other ideas. At this point it is up to them and anything you do is likely to cause more harm than good. As hard as it is to sit on your hands, that's the best thing you can do. Actually, at times like this, I've found the best thing to do is leave the house for the day so I'm not tempted to check on them every 5 minutes.
