I don't know about it being a great hatch. I set 37 eggs. They were shipped eggs so I did end up with 13 hatched out and one is in the hatcher now trying to get out. He is a late one all the others were out when I got home from work last night. So I am hoping he can get out of the shell. It is in there peeping away so I think it is still strong. After I took out the hatched ones this morning I upped the humidity again just in case some of the others were still good and sure enough this afternoon I see a pipped egg.
