Diary & Notes ~ Air Cell Detatched SHIPPED Chicken Eggs for incubation and hatching

I need some help with understanding this one....
[COLOR=0000CD]Development of a method to control the water evaporation of hatching eggs during incubation[/COLOR]

[COLOR=0000CD]ABSTRACT[/COLOR]

[COLOR=0000CD]Three experiments were conducted to develop methods to control the amount of water loss and to evaluate the metabolic effects of water condition in the White Leghorn breeder eggs during incubation. [/COLOR]
I have working with a wonderful gal to help get more silky ducks hatched, she says there is a major issue with weight loss in hatching them even running dry, cooling and misting. I am feeling her pain. I so wish I would have weighed these eggs, she is sending another batch out today, these I will weigh from the start since I have a new battery for my mini scale. it seem there are issues with weight loss, so I am researching all avenues and for the life of me I cant tell what this abstract is telling me! In addition to the following, I may or may not HOLD the eggs from incubations for several days, she has marked them and none will be older than 4 days and the eggs came in a days time last time she sent a batch. So I am thinking on watching cells and perhaps setting at day 10 mark. Any thoughts suggestions are welcome. Again the current eggs are in the cabinet bator and have been run dry, I have been misting them about 5 times a day, they are growing strong, but air cells are small. I have just read that you should NEVER mist eggs with a water that is the same as or cooler than the egg temp. the research paper said that the eggs actually draws the liquid inside and bring bacteria with it instead of the opposite, always use water a bit warmer than the egg itself but not hot. Throwing that out there for you coch as it makes sense too! @ozexpat @cochins1088 at everyone else that may have time to read it!! Can you PLEASE put their findings from that abstract in laymans terms? I really want these to hatch : ( and do better with the next set of eggs as well. What I want to know is, did drilling holes into blunt end of eggs reduce weight loss? what size and amount worked? What effects did it have on embryo health? I still have not run into a trial on sanding of eggs, if anyone has one please please please message me it!

When commercial hatcheries wash eggs they do it in water warmer than the egg to prevent the water and potential bacteria entering the egg. It stands to reason that the same would apply to misting. The study basically shows that even of you drill the right size hole, the carbon dioxide is much lower in the air cell. This deceased the chicks response to hypercarbia and it's need to get out of the shell. The increasing carbon dioxide level on a normal egg causes the chick to externally pip. The water loss improves but hatchability does not. I found no increase in hatchability with late hole drilling in my experiments.

OMG I always get sidetracked running into new info....  pasting this so I can go read it later!!

[COLOR=B22222]Since the chick will not draw the yolk sac into the coelom until carbon dioxide levels rise, placing the entire egg within a partially sealed plastic bag with a moistened, sterile gauze or re-sealing the eggshell with wax or Elmer’s glue may also be indicated.    [/COLOR]

This may be worth trying.

If I had the time, money and access to eggs I would give it a try

Hahahahaha. Sally I can't understand what I'm reading. Too distracted by your avatar. The butt.

During the last third of incubation the chorioallantoic membrane, which lies over the inner shell membrane, secretes a weak acid that dissolves the inner lining of the shell and provides the embryo with calcium to form its skeleton. http://www.aemv.org/members_only/2011-big book final.pdf






THE EGG BUDDY!
https://www.avitronics.co.uk/what_buddy_offer
Your troubles are over!!!

During the last 9 years we have been working at taking the guesswork out of incubation. After a terrific amount of work and research we are pleased to announce the arrival of Buddy, the first and only digital egg monitor in the world that has been made available to those involved in egg incubation.

There is no heat radiation whatsoever, so Buddy is completely safe.
If your egg is fertile then Buddy will tell you by around day seven or eight.
You simply place your egg in the egg compartment, close the lid and press the "on" button. You will instantly be given information from the onboard screen via a flashing heart, Pulse readout, and three-digit heart rate. (You will be amazed how rapid a chick’s heart beats)!
If the chick is moving then the Buddy egg monitor will tell you. When the chick settles the readout reverts back to heart rate. If the chick is not alive Buddy will let you know, showing a black still heart, a flat Pulse line and zero heart rate readout.
