Egg Hatching 101: Day 3


We are on Day 3 of our Egg Hatching 101 series, which means Day 3 of development for the 13 eggs in our incubator. As I have mentioned before, we use a Brinsea Octagon Advance incubator, which has a great digital display showing the temperature and humidity levels (shown above). You can manually alter the levels if needed, but it comes preset for chicken egg hatching and I've rarely had to mess with it.

One handy thing about this display is that in the lower right corner of the digital area (where there is just a blank space), a "P" will flash if the power has gone out at some point. We talked yesterday about things you can do during a power outage to keep your eggs warm, but what if you aren't at home when it happens and you have no idea? The flashing "P" on the screen gives you a heads up that something interrupted the power, and though you can't do anything much about it, you will know to candle your eggs carefully in the following days to make sure that the embryos inside show continued growth.

And, as a side note in this, if the power DOES go out, as soon as the power is back on this particular incubator goes right back to cookin'. It will work to get the preset temperature and humidity back as quickly as possible.

So on to Day 3... what is happening in our eggs today:

  • Head begins to turn
  • Tongue, tail, wing buds and leg buds begin to form


If we were to crack open one of the developing eggs today, this is what it would look like inside:

The red blob area in the center of the yolk surface is the developing chick. Remember yesterday when I mentioned that we will try candling our eggs tonight to see if we can pick up any veining? This, above, is the veining we will be looking for. It is still early, and some people don't candle until Day 5, but we'll see if anything is visible, and if so we will post the photos tomorrow. (We can't candle until after dark tonight, otherwise we won't be able to see anything at all.)

This is a pretty cool photo of a chick embryo on Day 3. Although it still looks like a tadpole, you can start picking out a few recognizable parts. (Photo credits: University of Illinois)

Weather update: We are still dealing with this Tropical Storm/Hurricane/Whatever Sandy that is blowing through. Lots of rain, lots of wind. There is a lot of flooding in areas around us but our farm is doing well. We haven't had any power outages yet (thank goodness) but we are still prepared with a warmed cooler if we need to "rescue" our incubator.
