    Last Sunday I new absolutely nothing about raising any type of egg/bird. Then I was given a opportunitiy to either
    A) try and give 9 duck eggs a chance to live
    or
    B) watch them being thrown in the trash. Despite my ignorance on the subject I decided to give it a shot.

    I went with B

    I quickly researched optimal temperatures and humidity for duck eggs (we think mallard) and put my nerdy engineering skills to work. Long story short I was able to put together a computer controlled incubator that regulates both temperature and humidity with an internal fan to circulate the air.

    I was able to get the eggs into the incubator within a few hours. I then immersed myself in learning all I could about the subject. Later that night I went to turn the eggs and (with my newly obtained knowledge) armed myself with a bright flashlight. I candled all 9 eggs and found 7 are very much alive and moving. It was very obvious that the other 2 were not viable.

    So, As of the time of this writing, I have 7 viable mallard (I think) duck eggs. I have been trying to determine how far along they are by candling them, tracing the air pocket and taking picture, then comparing those pictures to online resources. I'm having a hard time feeling confident about what day they are on. I could use all the help i can get.

    My biggest reason for wanting to know the age is so I know when to change the temperature/humidity, also so I know when to stop turning them.

    Here are the pictures I took tonight. The line on the egg was traced roughly 36 hours before the picture. I apologize for the quality/blurriness. I was trying to keep several small children at bay while taking these pictures

    I was thinking they look to be about day 23ish but I have no confidence in the figure... What do you all think?

    Best advice I could give, sence age is not known, is to keep turning them till they pip. Then stop turning and jack the humidity up and cross yer fingers.

    I'd say your guess is as close to dead on as possible at this point, lol... easiest way to figure out when to stop turning and up the humidity is to watch for drawdown... as soon as the air cell dips down on one side drastically, they're getting into position to hatch... :)

    Wow! What an awesome experience/opportunity! They look healthy from the pics. I would say around day 20ish. Keep reading and learning and there are lots of great people on here that can help with any questions and hatch time. I can't wait to see what kind of ducks they are! Good luck!

    Thanks Ruby!

    Its funny how I seem to get sucked into my hobbies, yet incorporate my old ones.

    I now have this incubator tricked out! 4 different digital temperature sensors (mixed throughout the eggs), and 2 humidity sensors placed on opposite corners of the egg area. I can then take averages from all these sensors to control my heat/humidity elements. This has helped a great deal in determine best fan placement to circulate the air evenly.

    Today I added the ability to remotely monitor this data from my phone or a web browser, including a live video/audio feed! I have this playing softly in the background while at work. Hopefully I'll get a nice "chip chip" warning after they've internally pipped.

    Very existing stuff! I really hope these ducklings make it...

    Wow! That's awesome! Wanna come to my house and hook up these incubators here? ;) Seriously though, how are the eggs doing?

    Thanks for all the great help everyone, I real do appreciate it.


    UPDATE / MORE HELP NEEDED...

    So the photos in my original post were taken on 7-5 (Tuesday) in the morning. Here are some updates on whats happened since.


    (Friday 7-8 @ 9 am) The black line is the new air pocket trace.
    [​IMG]




    9 Hours Later (Friday 7-8 @ 6 pm) I then Candle the same egg and it showed even more air pocket growth.
    [​IMG]




    21 Hours Later (Saturday 7-9 @ 3pm) This pic show a third and final trace of the air pocket (Pic taken from the video feed inside the incubator) A LOT of movement!
    [​IMG]


    After this last picture, I thought for sure I was on day 27 or 28 so I went into "Lock-Down". Cranked the Humidity up to 75 - 80% and brought the temp down to 98ish degrees F.

    Oh coarse now I'm having doubts. Am i premature in my Lock-Down? I to late in my lock down? Should I have waited until I was sure an internal pip occurred?

    Also noteworthy, only 3 of the 7 eggs air pocket was this far progressed. 2 others have moved passed the orange line (from Tuesday 7-5), but not far passed. The remaining 2 are somewhere in the middle (in between the orange line and the final black line).

    Still no signs of pipping (however I haven't opened the incubator to candle any).

    I read all these things about "Lock Down" and how important it is, hence my concern.

    So should i just keep waiting? Is it really that dangerous to move the eggs (to candle them or float test them) during lock-down?

    Thanks for your help everyone!

    That looks like drawdown!! Yay! The others may take just a bit longer to get there is all...

    As for lockdown, I hatch Call ducks frequently and candle constantly at the end, no issues... float test really doesn't do anything more than candling, but I would only float test way past their due date, or in your case a couple days after the others had hatched if any don't...
