The 5th Annual BYC Easter Hatch-a-long!

[TJChickens]

its funny you mentioned the closed pores!

I am actually working on best storage for viability up to 14 days and in my investigations (again wishing you were on the diary thread to help me navigate through some of it, hint) anyways, in my investigations I ran over some interesting stuff, that yet again opposite of our thinking! So before I add this cool info to the article I want to understand it completely! its quite cool for those of us that need to incubate in bulk and dont want to set every week for sake of sanity too!

Temporary heating before incubation and enclosing eggs in plastic bags during storage improves hatchability, especially when storage is prolonged.

The changes in albumen pH during storage are discussed in so far as they provide a possible explanation for relationships between environmental conditions during storage and hatching results.


Its mentioned here as well: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.138.798&rep=rep1&type=pdf



and here is yet another find that defies our teachings!


1 Conclusions
"In conclusion, storage in the small end up position or turning during storage can significantly
reduce early and late embryonic mortality. It will increase your profits, especially in eggs that are
highly sensitive to prolonged egg storage."http://www.hatchtech.nl/aboutus/articles/Alternative%20Egg%20Storage%20Methods%20Small%20End%20Up%20or%20Turning.pdf


2 "CONCLUSIONS
Storing eggs with the small end up is an alternative method to improve hatchability and to reduce egg weight and hatchling weight losses in eggs derived from young and old breeders stored up to 14 days."http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-635X2012000400003

I know you're talking about evaporation here. But I heard somewhere that the aircell is more protected in shipping eggs if they are stored and shipped pointy end up. I have never had the nerve myself to try it or request it.....You think there's anything to it? Maybe it's just that with less evaporation, a smaller cell is stronger than a larger cell.?

Storing pointy end up ONLY improved hatch rates in eggs stored 7-14 days. Its is NOT recomended for shipping

A smaller cell is indeed stronger than a larger one, I would not ship pointed end up, my sense tells me that if I have an air bubble on the bottom it will do what gravity wants it to do, adding movement to it could in fact prove fatal. Adding, I didnt want to send out confusion, I just meant as storage, if you read some of the info, it is for long storage. again not shipped eggs. Its important to us here, to be able to store eggs so we can fulfill large orders. HOWEVER the plastic bag deal may be of interest in these situations

I have been only hatching eggs for about 17 months so I could be called a newbie.

Because I wanted to get the best hatches possible in the Philippines, I hatches more than 20 shipped egg sets in SoCal and either sold or gave away the chicks (my rental apartment does not permit chickens lol). I followed all the guidelines of the times and found myself with dead in shell chicks. I also spent many a night on Sally's thread working with people to get their stuck chicks out.

All the research I was reading said that turning was critical, yet we were all letting our precious shipped eggs rest for days and up to a week. Something was wrong. I changed my practice and studied the results. After more than two thousand shipped eggs I can say that it is clear how critical it is to get eggs turning within 48 hours. Any longer than that and my dead in shell or need to assist rate climbs.

I turn all eggs at 12 hours. When I am hatching in the usa with a nice controlled dry hatch, those with really bad air cells hatch at the same rate - from zero for rolling cells to about 20% for jiggly cells. My assist rate is zero and my dead in shell id about 5% on shipped eggs. Calculating success in shipped eggs is different than with local eggs. If you are doing everything right on local eggs you should be at 88-95% of eggs you set. While I record my percentages of eggs set versus hatched with shipped eggs to evaluate vendors and shipping methods, what happens to an egg before I set it is out of my control. An egg that is non viable could look perfect but candle clear. Everything from hen nutrition, to age of eggs when shipped to travel vibrations can cause a clear at 7-10 day candling. All my research is based on improving hatch percentages of viable eggs. The most significant improvement came from turning eggs early. Now temperature, humidity and ventilation control are critical and without them, you will fail catastophically but if delayed turning causes a dead in shell improvemnt as signigicant as 10-15% - I will take three more chicks in a clutch of twenty.

Sally has been on board with this thinking through her own research and modified her hatching 101 article probably 6 months ago. The concept is new on BYC. Lots of people giving advice are following the age old procedures and it will take a while for the culture to change. Hatchalongs like this are a great time to get everybody together and discuss new methods, and share our results.

Good luck with your hatch.

oh dear....I have been so careful with all my shipped, damaged air cell eggs. They are all upright and I didn't turn them for the first several days. Then only started slightly rocking them in the cartons three times a day. It sounds like they will all be stuck now. I had a bunch in a styrobator with a turner. I turned the turner on at 5 days and just figured out that it isn't turning. So those went 7 days without turning

It didn't make any common sense to me either, because of air rising.... There is somebody who is insisting on shipping their eggs upside down. They sounded very sure of themselves in what they wrote, but If I can find them again maybe I will give them the link to this storage discussion...

so marshie has officially been broody for 5 days now and she is hard core. she will not get off that nest even if I reach my hand under her!

I was thinking about going to my breeders but he just closed. I wanted americuana eggs from him. he is closed tomorrow as well.....and I cant go any time nest week......so I have no idea where tro get eggs! I feel im on borrowed time because marshie may break her broodiness but last time she was broody she stayed for about 3 weeks....so I think I may have time.

if I cant get any eggs from my breeder, I think im going to place my first bid in the 24 hour auction thread for eggs

So this little girl hatched late last night:




Here's hoping the other egg hatches too!

So precious! I want to snuggle with her!
