I started with 18 eggs I bought from a seller on ebay. 13 made it into the hatcher (candled alive and well). 4 pipped on day 19 to hatch day 20, 1 pipped and died , and now its day 22 with no progress on the others. No movement, pips, cheeps nothing.... Is this normal for them to be so far apart? I'm new to hatching a worried about the little ones. (they are a d'uccle mix) Incubation was 100F and 45-50%, hatcher is 99.5-100 and 65%. All went in on same day same time 4/30 9pm.
