I set 16 BCM eggs and 12 Golden Coocoo on the 15th of Sept at 8m and was expecting all to hatch by yesterday. I had two hatch last night at 7:00 pm and three more pip by 10m and had three more hatch out this morning and then three more since. I have several more pipped today however about 9 have not pipped but are rocking. Is it usual for the hatch to spred out over three days and two of those days are past the due date? Or did I count wrong? Incubator is a LG with fan. temp held true at 99.5 from the beginning also the hummidity was good. any ideas?
