Well...the egg we had that had the shell over the air cell cracked (pretty badly) and had fluid in the air cell...HATCHED!! 2 days early even. Chick is bigger than the others we have ever hatched out. It is a silkie cross. The other silkie cross hatched out 3 days early and the silkie hatched yesterday. All seems well. Thank you everyone for the advice and help...I am really glad I didn't toss out the broken egg.
