Maybe your LF eggs have a different shell porosity than your bantams, and that's why the LF air cells look a little small?? I've been reading some cases where mixed batches don't do as well. For me, I'm not doing my blue/green eggs with my Orloffs (tinted, kind of peach eggs) because they lose moisture so differently and it's hard to have optimum conditions for both.
Just a thought.
I wonder about setting Banty eggs with regular size eggs with a still air incubator . The top of egg temperature is critical with still air incubation. I would think the case would be set the temp to the highest egg. I also think temperature spike to the high side could be the cause B . Day 22 no movement Give them a little more time at least through 23 . book says 25 but I haven't hatch any later than 22 my self . it is the end of 21 for me and I don't think any more will hatch . Unloading the incubator and vet sexing chicks is a chore .still don't have a count . I feel like I have many right . Vent sexing and backing up with feather sexing . But If I didn't have the desk magnifier lamp it would be harder . More Pullets than Roos . guess that's good . Anyhow if you don't see signs of life by the end of day tomorrow pull the plug and set up for the next set sorry .
That might be it though. I just wonder why it got all the way to day 18 though.....
Glad you have lots of pullets!
