Update: The Buff Orpington egg hatched around 8am and one of the Barred Rock eggs hatched around 2am this morning. But I'm worried because the one that has been pipped for a while still hasn't progressed besides another chick pulling off a piece of shell for it.
I'm trying to be patient but I keep feeling like I need to do an assisted hatch. Is it normal for eggs to take THIS LONG? The other three had all pipped sometime during an afternoon or evening, and been hatched in the morning. The final unhatched BR egg has not changed or chirped or wiggled for so long, that I think it's dead or needs help. Is it common or possible to just naturally take this long? Should I do something?
It can be normal, depending on many conditions ranging from egg storage time and conditions, size of eggs, breeder nutrition, turning, temperature, humidity, etc..
I had 13 eggs due to hatch 45 hours ago. 2 hatched on time, the rest were malingerers. 7 chicks out now and two more still hatching.
I know some of my problems were egg storage time, insufficient turning during storage, mixing large and small eggs, among other things.
The first to pip and zip didn't make it out till this morning. I thought it was dead because it didn't move when I tapped on the incubator which caused all the others to start hollering. I went back a couple hours later and I couldn't tell which one it was because he was running with the others.
His issue could have been breeder nutrition because I hadn't spiked that early enough.
Egg weight was also a gram or two low at the end that tells me the humidity was likely low during incubation.
