I finally called an end to my test hatch on day 26. Official tally... 1 out of the 6 eggs I originally set actually hatched. ARGH! Two were infertile and one was an early quitter, all tossed around day 14. At lockdown we had three viable eggs with plenty of movement inside. Bright and early on day 21 I had a beautiful little blue sexlink pop out, and after that there was a whole lotta nuthin! I thought I saw movement in one so I started to open it to help on day 26. I figured at that point it was unlikely to come out on it's own. It was definitely breathing but not moving and not cheeping. Put it back in the bator wrapped in a damp washcloth and left it for a few hours. Later I went back to do a little more work but it had passed. I admit that opening it may have killed it sooner but I am 100% certain it was not coming out on it's own. I opened the egg up and found a little splash Marans I don't think it was turned correctly to pip the airsack. I didn't pull it all the way out but I couldn't find the head or beak. It didn't seem overly large for the egg so I don't think that was the issue, and it was surprisingly easy to get the shell off so I don't think the shell was too thick to pip. There was some bright green and white stuff on one side - not sure what that was - bacteria maybe? Any thoughts? Did an eggtopsy on the other one and it had definitely expired several days ago. Didn't stink yet but the membrane was very dry inside and some super gross grey liquid came out when I punctured the membrane. Thanks to that liquid I lost any desire to open further so I don't know much else about this egg. Judging by the other two that made it to lockdown I don't think I had a shrink wrapping problem and my humidity was good for the entire hatch so I'm not worried about that. This one was definitely viable at lockdown, must have died sometime shortly thereafter. From what I could tell there was no internal pip. The shell on this one was really tough to get into so if it actually did pip internally that could have been the problem. Now I'm just trying to figure out what happened! This was my first hatch in my homemade wine cooler bator. It's got a fan and the repti-temp thermostat. Humidity was a steady 40 - 45% through day 18 and 60 - 65% through lockdown. Temps were very steady, keeping within .2 degrees of 99.5 throughout the incubation period. These were eggs from my flock, not shipped. I trust my thermo/hygro but one thing I will do before my Silkie eggs get here at the end of the month is go out and buy another thermometer just to verify that mine is reading correctly. I'm going to clean the bator like crazy as well just in case I had some kind of bacterial problem. Anything else that might have caused this terrible hatch? Anything else I should think about doing before my next hatch?
