Are those lines where you are now? If so, they are a very small area for the chick to pip into. How are you measuring your humidity? Did you calibrate your hygrometer?
We all have ruined hatches in some way or killed baby chicks along the way. Hatching is more of a skill than I could have imagined and an addiction-lol So, please don't beat yourself up too bad on this if it doesn't turn out okay. I am hoping for you that it will. I don't know how to advise you on this. I would probably try and keep the humidity on the lower threshold of the hatching spectrum and candle tomorrow.
Is there a way you can candle them or see in them at lockdown to monitor their air cells? I know sometimes if you have a bright light and light eggs you can actually see the air outline without opening the bator.
I did not calibrate the hygrometer and I should have. It's definitely a skill. One that I'm not too good at yet. Ugh I'm just hoping if I let them run dry a few days the air cell will at least have a little time to get bigger. I will definitely check them tomorrow to see if the cell has grown at all. I'll try to take a picture too because I think they may be a little delayed in development as well so hopefully they will have a few more days for the air cell to grow. I'm wondering if I should put them in egg cartons fat end up so maybe when they pip, the extra fluid won't get into the air cell. I read about that somewhere on here. I love candling them and seeing them grow and will feel terrible if I get them this far just to die. Ugh so many highs and lows in this process! Thank you for the advice. Much appreciated!
Hey Herbgirl- How's the hatching going? These are your own EE's, right?
