If you did your part up to this point, and your eggs were fertile, you'll have chicks.....If something went wrong its too late to worry bout it now..... No wiggle'n is not a problem.... THe best thing you can do is lock them down, bump up your humidity and dont open the bator for any reason.... no candling, no float testing..... lock them down and get your brooder ready for chicks..... Good luck and post pix in three or four days......
