Lemme guess?

really leave me alone.
 
no what I advised for temps is what you should shoot for

yep  hang on a secongd





There are two types of sticky chicks

Sticky embryos (embryos may be smeared with egg contents / yolk residual present) (yellow jelly/jello or other fluids)
HOWEVER, a green and gray tinted fluid can be caused from osteomylitis or meconium) 
causes: any/all combination of the following:
     high average incubation humidity
     low incubation temperature
     lack of sufficient ventilation
     too many drafts of outside air in the hatcher
          BREED ISSUES:   Always avoid cross breeding in breeds that carry lethal genes.
          are we aware of Lethal genes for this breed of duck Rav?
  
Embryos sticking or adhering to shell
causes: in any/all combination of the following:
     Low incubation humidity (especially during hatching)
     Excessive ventilation~ reduce rate but maintain minimum air exchange to prevent suffocation of embryos.
    
 
To confuse you a bit more, the amount of water that a chick has in its own tissues (not the albumen) has been shown to increase during incubation under perfect conditions; however, rate of egg water loss is found to have no effect on embryonic water, how could this be if we get big wet chicks from high humidity? Makes you think outside the box, perhaps it is in fact LOW TEMPS not the hearsay on humidity? Although AGAIN combination is usually the factor. 
 
 
TEMPERATURE:  Changes in temps during incubation result in losses.  Incubation temperature is one the most critical factors during embryo development, AGAIN studies have shown the optimum temperature is more 99.9.  NOT FORGETTING that also its optimal to drop in temps during hatch, as I suggest in my article Hatching Eggs 101 in the lower day 18 section.  So it may be worth a shot for you, and I am not clear on your temps or calibration, Hammond found that a bit higher incubation temps increase chick initial body weight believe it or not, at the higher temp 99.9 the higher the rate of egg water loss in the first 16 days of incubation. What I have found is when I incubate at a slightly elevated temp 100 to 100.5 calibrated I have much cleaner hatches. They found that its the opposite with low temps, body weight of chicks were less. Then you get into the additional factors of adding low high temps with humidity and ventilation....  Best we can do is work these areas to achieve absolute and relative weights. IN KNOWING THAT and then factor in that EACH EGG & breeds are different in age, air cell size, genetics etc.

thanks again. You always have great information! I am hoping to get my hands on some maran eggs this spring and will try the adjustment.
