How much you wanna bet the rest of my babies hatch tomorrow when I'll be so busy I can hardly think straight, instead of Thursday when I can watch them all day if I want to?
They could hatch either day.
All 3 button quail are doing well.
I am now waiting on the 12 coturnix eggs.  I have not candled them BUT
1 is damaged (probably no good BUT I smeared it with glue in the damaged area and it doesn't stink yet. It's been five days since then.)
2 or 3 feel lighter than they should. However, it's not over until a couple of days after all the others hatch!
So, probably 8 hatchable eggs.  
The ones that feel too light are NOT the fault of my incubator. I suspect it's the female bird in this case. Her eggs are sometimes abnormal. About every 3 weeks she lays a soft shell, even though she has plenty of calcium. She also lays thin shelled eggs on occasion -- so thin they break in the nest. Once in a while she has a blood spot in her eggs, too.  I figure her eggs probably aren't hatchable, but tossed them in as extras just in case.
