do you know what you're humidity is at? this one looks a bit dry, but it's possible it bled a bit when it pipped. the membrane on the blue? one under the thermometer probe looks a little dark too. but the pictures blurry so it might not be it's hard to tell.
aside from the yellow/brown of the membrane these guys looks good. The larger pip hole on the bronw one is just a secondary pip it's doesn't look like it's trying to zip yet.
It sucks loosing chicks. I had a couple of really good hatches and a few pretty bad ones. my most recent I got less than 50% to hatch, with a couple of special needs chicks too. :/ all but one was a malposition too. they all got out un-assisted though which was a plus.
biggest thing with the last few days of incubating is giving them more than enough time. in 3 years of hatching (learning how to assist and when) the worst thing is going in too early. I've only had one chick survive having it's yolk on the outside. and that was this year.
hope you get lots of babies.
they get really quiet and sleep. mine are usually 8 - 12 hours being quiet before they make a second pip and then its still around 3 more hours before they start zipping. if they've pipped the wrong end it's even longer.
my one that pipped the wrong way is chirping and trying to zip but it looks like they are stuck. I had another one pip the wrong way but they haven’t done anything. Then I had another one make a tiny external pip a few hours ago but nothing else. I’m honestly so worried I don’t know what to do.
