Tonight the eggs reached another big milestone: Lockdown. This means we’re in the home stretch, and we took the eggs out of the automatic turner and laid them down on their sides so the embryos can get in position for hatch. We may even see them start rolling around a bit in the next day or two as the chicks move inside. So, we’ve started up our live stream (via Ustream) to keep an eye on the incubator.
The main thing about lockdown is that the humidity requirements are higher, especially at high altitude. I’ve been weighing a few of the eggs to track how much liquid they’ve lost (chicken eggs should lose about 13% during the course of incubation.)
They seem to be pretty much on track in terms of weight loss and air cell size, so we’ll increase humidity to around 70% from now on. (We’ve been keeping it around 50%, but it should be higher during lockdown so the shell membranes don’t dry out and “shrink-wrap” the chick.)
The other thing about lockdown is that we’re not supposed to open the incubator from now until the chicks dry off, so it’s going to be a long (and possibly anxious) few days.
And just to keep things interesting, it looks like we might get yet another late season snowstorm tomorrow. That’s 3 Mondays in a row now, and I’m convinced it’s because I have eggs in the incubator (Colorado, you can thank me later.) But the generator’s ready, so bring on the snow. I might even wash my car tomorrow.
