We're currently on day 11 of our 21 day egg incubation with the new Hova Bator.  We've been candling our eggs periodically to make sure we don't have any failed eggs so they don't end up making a mess and I gotta say it's a pretty cool thing to see life being created.  At only 6 days of incubation you can see blood veins inside the egg that feed off the yoke and also the embryo moving around.  The dark spots are the eyes and heart as it moves around in there.  We just use a high powered flashlight to see whats going on.  Out of our 40 Rhode Island red hen eggs we have only had to remove 2 so far.  The Hova Bator was working wonderfully until the small computer fan that keeps the air circulating started making noise and rattling around.  I was getting worried because we're half way through the incubation period and we don't want it too poop out on us now. So with some bolt-tweaking and the use of a rubber band, we got it to run smooth again for now.  Before we start another batch were gonna need a new fan.  I cheated and found a youtube video of what we see as we are candling so this isn't our own video.  We may have some baby peeps for sale soon ; )
