"Settling" Shipped Eggs: Necessary? With Auto-Turner? - Page 8

it

 basically says same thing as the redwood incubation tecniques except she goes into little more detail about blood rings,  she said in the letter that the embryo began to develope early on and due to unpressurised air travel it scrambles the dna and that is why hatching eggs are picked very fresh and stored in cool location to prevent the germ from beginning to develope.. and embryos that are able to begin to re-assemble cannot find ability to attach itself  to inside of egg..due to loose air cells..she recomended allowing them to sit upright in incubator undisturbed for 7 days . her letter also says never just be in a hurry to get eggs into incubator...this is shocking to embryo if the egg is not rested and slowly warmed up may cause condensation on inside of egg shell and bacterial growth handeling hatching eggs that are shipped is chalanging but so rewarding when you hatch high quality breeder birds..always wash hands when handeling these eggs and dont beat yourself up if all of them do not hatch ..this method will help increase your hatch rate..when i have a little more time i will re-write it if i have to..its a good tip for those who like to buy from breeders..

 somone a couple years ago had a short films on youtube showing stable air cell and shipped air cell..but it has been a long time i cant remember what they titled it..

i just got some more hatching eggs and i found an anomoly...one of the air cells is on the side of the egg..it just happens every once in a while that is one that might need a little assistance at hatch time..or sometimes they just figure it out themselves..

And I thought I was a BYC addict...

Lol... I agree I need to get out more! I went to a chicken swap today.... Then to home depot to buy that 208 lumens flashlight (which works excellent by the way!) does that count?

I just put my first ever hatching eggs(shipped) into the incubator yesterday.  I let them get to room temp before loading them, but I had never heard of letting them sit still in the incubator for 7 days.  I just turned off my auto turners.  Do you think I caused irreparable damage by auto turning them for 1 day?  Thanks so much for all your wisdom and experience.

Here's the text, copied from that link:

 

• Here it is--Remember, these instructions are for shipped eggs:
•  
• it says allow eggs to sit 12 - 24 hrs in a place where if they are cool , they can warm up slowly. leave them after carefully unwrapped  upright inside cartons and close lid so they will not warm up too quickly. eggs that warm too quickly , or cool too quickly are shocked . causes lower hatch rate.one of the reasons shipped eggs do not fare well..slow cooling and heateing give better success. cool eggs can remain in cool area, remember warm very slowly, do not ever shock shipped eggs or any egg by throwing it in the incubator , this causes condensation on the inside of the cool egg and bactieria begin to grow and kill the egg. always warm eggs slow;ly,.... try to keep already warm eggs stable, do not allow those to take sudden chill. never be inpatient to get eggs in incubator.warm eggs that take a sudden drop in temps will kill the developing germ. even in late development.
•  
• you should have your incubator up and running days befor they arrive and be stabalized.
•  
• place eggs upright carefully in turner trays or cartons if hand turning.
•  
• allow shipped hatching eggs to sit upright position in incubator with egg turner off for 7 - 10 days , this allows air cell to stabalize and give the germ time to organise and get a healthy start without constantly being moved disturbing delicate vessels and cell formation. shipped eggs most likley suffered some damage, constantly disturbing this formation will give lower hatchs.
•  
• depending on damage, turn your egg turner on day 7  and allow eggs to be turned for the last part of incubation. this excercises the embryo and prevents the embryo from laying in an area where waste product inside the eggs collects, helps circulation and proper development.
•  
• Run your humidity lower than recomended to help air cells to dry down and helps in healing.unless eggs are coming from very arid regions where the cells start out larger due to rapid evaporation.
•  
• do NOT lay shipped eggs down on thier sides in most cases during lockdown. it is best to sit these in slightly cut down paper cartons... do not use styro cartons as they heat and release chemicals that can be toxic. cutting the side of the carton down just a little ensures pipping can occur without running into carton wall.
•  
• sometimes befor or during shipment conditions are right for the germ to begin to develope, this is the most delicate time for a hatching egg. and the time when most are damaged ..tiny blood vessels are beginning to form, and cells are deviding and organizing , and being shocked with sudden temp changes and shaking .so dont beat yourself up if all of your shipped eggs do not hatch, more than air cell damage , the germ itself became disorganized and cannot re build itself. that is why the freshest shipped eggs are most desirable.  you will get a larger percentage to hatch using this method and conditions in your incubator are correct. it is so worth it to buy from a good breeder. often it just isnt possible to drive across the country just to pick up some eggs or birds so try this method and happy hatching,
•  
• remember post office personel are not trained in handeling these products , thier job is just to move item  place to place..hopefully there was not a drastic temp change or prolonged air flights in sub freezing cargo in low 02,  30 thousand ft plane ride
