Just put our first 11 serama eggs in the bator yesterday...... getting another doz monday for the other bator as these have alot of rolling air cells. SHIPPED eggs

Quick tips on incubating these? 99.5 with 40/45% humidity until day 18? then up to 60/65% ?

Thanks everyone! And Hello from PA!!

I actually let mine sit for 7 days in the incubator before I start to turn them. Out of 3 batches of shipped eggs I ended up with 4/1/1 chicks.

Amazingly, my last batch of eggs,were not turned for the last week AT ALL because I was in the hospital and had a 100% hatch, which prooves at least the last week isnt as important. I have a bunch of "technical" lol information that I saved in my Article from incubating thread, https://www.backyardchickens.com/a/hatching-eggs-101

This is a paste of what I saved when I researched this issue..... but like I said this time I am trying to turn them HOWEVER I have let them sit 24 hrs before setting. So far the only diference in serama eggs are the humidity?????????????

NOTES: The yolk of an egg is held in place on each end by what is called Chalaza. These are delicate cords that keep the yolk centered in the egg. When you crack open an egg, you notice a white stringy thing on the yolk, this is the Chalaza. When eggs are shipped they encounter many things that are not favorable to their well being. Postal handlers that toss the packages, machinery that sorts the mail, bumpy vehicle rides and the such. So by the time the eggs get to you they are pretty much scrambled inside. So if you are going to by eggs and have them shipped to you, be aware that the viability drops to near zero. Yes there are those rare instances when they arrive safely but it is always a gamble. http://fluffybottomsfarm.blogspot.com/p/incubating-and-hatching-eggs_9.html



http://dev.biologists.org/content/5/3/293.full.pdf A Critical Period for the Turning of Hens' Eggs
SUMMARY
1. Turning hens' eggs between the 4th and 7th day of incubation gives a
hatchability similar to that of eggs turned throughout incubation.
2. Turning the eggs between the 8th and 1lth day gives a hatchability similar
to that of unturned eggs.
3. New evidence is presented that absence of turning leads to abnormal
adhesion between the chorion and shell membranes.​
4. The mechanism by which turning effects development is discussed.

Effect of Egg Turning Angle and Frequency During Incubation on Hatchability and Incidence of Unhatched Broiler Embryos with Head in the Small End of the Egg1 O. Elibol* and J. Brake†,2 Abstract

The effect of turning angle (from vertical) and the interaction with turning frequency during incubation on fertile hatchability, embryonic mortality, and the incidence of embryos with head in the small end of the egg (malpositioned) was studied in 2 experiments comprising 2 trials each to determine if a turning angle of less than 45° could be successful. Hatching eggs from commercial broiler breeder flocks from 55 to 61 wk of age were utilized, and turning was for 18 d. Eggs were subjected to turning angles of 35, 40, or 45°, with a turning frequency of 24 times daily (24×) in Experiment 1. Turning angle had no effect on fertile hatchability. However, the incidence of separately enumerated, malpositioned embryos was increased by the 35° angle, compared with both the 40 and 45° angles in Experiment 1. Eggs were subjected to turning angles (from vertical) of 35°, with a turning frequency of either 24× or 96× daily, or 45°, with 24× turning in the 2 trials of Experiment 2. Turning angle and frequency had no effect on fertile hatchability or embryonic mortality, but the incidence of separately enumerated, malpositioned embryos was increased by the 35° angle with 24× turning, compared with the 35° angle with 96× turning, and the 45° angle, with 24× turning, in Experiment 2. These data demonstrated that the incidence of malpositioned embryos was increased by a reduced turning angle, but that this effect was ameliorated by a concomitant increase in turning frequency.


Relevance of turning Written by Gerd de Lange see page for full info.....I FOUND the one that I actually understood here:
http://www.pasreform.com/academy/frequently-asked-questions/incubation/26-relevance-of-turning.html
Broody hens provide optimum conditions for embryos developing in the eggs they are sitting on. The brood patch provides heat from one direction only, and the eggs at the side of the patch are cooler than those in the middle of the nest. However, because the broody hen regularly turns and moves the eggs in the nest, uniform egg temperature is achieved.
In commercial incubation, we try to mimic the natural conditions in the nest. From the point of view of uniform egg temperature turning of eggs seems to be of less importance in modern incubators. Are there other reasons for turning eggs?
As summarized by Deeming (2002), egg turning is essential to normal development for several reasons.
Egg turning

  • Prevents adhesion of the embryo to the inner shell membrane.
  • stimulates the rate of development of the area vasculosa (the membrane which grows around the yolk and is rich in blood vessels). The area vasculosa is important for sub-embryonic fluid formation, as well as for yolk uptake later in incubation.
  • allows normal transfer of albumen proteins into the amniotic fluid, promoting optimum use of the albumen.
  • supports the growth of the chorio-allantois (the blood vessels right under the shell) to maximise oxygen absorption.
  • embryos in unturned eggs grow at a lower rate compared to embryos in eggs turned each hour over 90˚.
  • facilitates movements of the embryo into the normal hatching position and reduces the incidence of malpositions in unhatched embryos.

Advice

  • Check the turning device before the start of each incubation cycle, as turning failures, depending on the moment of occurence, are detrimental to results.
  • Check and maintain the turning device regularly, to prevent a breakdown during incubation.
  • Make sure that turning does not produce shocks or jolts, as this adversely affects hatchability and chick quality.
  • If necessary, check and adjust the turning angle: 45˚ is optimal.
  • Not turning for the first 12 hours in the setter is advised, based on our practical experience and especially when eggs are transported to the hatchery on the same day as setting. Eggs need some rest time to restore their ‘internal balance’.
  • Turning is not absolutely necessary after 15 days of incubation. Especially in incubators with insufficient cooling capacity, it can be beneficial to leave the eggs in a horizontal position to facilitate increased air flow (cooling over the eggs). In some modern setters, there is also the option of turning to three different positions, e.g. 45 minutes each in right, horizontal and left position).

Since I started letting them sit for the first seven days my development rate has increased dramatically on shipped eggs. Before I was lucky to get 3 or 4 to start and now I get between 75-80%.
 
Sally Sunshine, thanks for the info. I actually read that whole thing. Feeling pretty smart right about now!! LOL! I just set my Serama eggs from Beth a week ago, with 11 heartbeats. Only 2 detached air cells , so maybe your mail truck hit a pothole.. kidding

. BTW I stumbled on the pic you posted on Pennsylvania Unite of the turkeys bound for processing. I kept thinking of it tonight as I was marinating that bird!! I just may raise my own next year because of that pic. So, thanks, I think???

I am looking for diapers and harnesses for my 3 serama and 1 silkie does anyone know where I can get them ,
And I have a question aobut my little whiteish hen , she is the same size as the serama and hatched from a serama egg but she is longer Im not sure how to describe it , the others hold there tail up high and there heads but she holds her self longer ??
