This evening, when I was letting our broody out for her poop, I checked her eggs very quickly and discovered that at some point in the last couple days this egg developed this crack. It may have happened today as the membranes are still very white. I candled to check for an internal pip and I didn't see one. The egg's (possibly?) on day 19 right now, and is on the small side so it may be one of our bantam brahma eggs.
We happen to be incubating some Jersey Giant eggs at the moment, so I brought this little one in and put it in the incubator to keep it from being further damaged. But the incubator's at least a week away from lockdown, so if this baby's still viable, humidity is going to be an issue.
There's a lot of territory to cover with nail polish. Are there any other suggestions?
Especially since the membrane appears to have a tiny hole in it. Nail polish won't fix that, will it?
And especially not if that's an actual pip, which I don't think it is... but maybe? I would expect a pip would be protruding, or at least flush with the shell, not dented in as this crack is.
