I am going into day 24 and still no pips after just 2 chicks hatched! I got a jap and and chick that I don't know what is!! this was supposed to be a nankin but obviously is NOT a nankin, I think I got the eggs mixed up with some of my polish eggs from the same coop b/c the nankins are with 2 WCB polish hens so this may be a polis-nankin cross which is really weird! it's solid black w/ a RC and no crest. so disappointing to not be a nankin! we didn't get any out of the last hatch either!! no signs of pips or rocking and I am going to have to open it and get the 2 babies out ... I want to let the eggs keep going just in case not sure what to do!!!
