I personally don't leave my chicks in the bator, I snatch them out real quick so they don't scramble other eggs. I have tried the turner, didn't like it. Tried the egg carton method, didn't like it. I like turning eggs three times a day. I don't usually help them out unless they've been pipped for a full day, and have not progressed. Especially if they are small eggs..silkies, seramas....then they do need help.
Good luck, just keep them in the bator for a while longer, sounds like you have some action going on in there. Now that the one that you have helped has had a nice air way cleared, let it set for a day, if you are seeing blood, it can wait a while before you do anything more.
