Egg pH

I have found that when I let my eggs sit in the fridge their pH goes down.  I have been getting Free-Run eggs and as soon as I get them home their pH is above 9 after about a couple of weeks their pH is around 8.8-8.6 or so.  I am not sure if it these specific eggs or not but for those that are having pH problems.  Try testing the EW as soon as you get the eggs home. 

Just a thought...I noticed that the longer I have had my eggs, the higher the ph.  So, let say I buy them and then in 2 weeks I use them for SU, the ph goes up alot.  But, If I buy the eggs, then use them within a couple of days the ph is too low.  So, I have learned...the older the better and I don't mean expired, just sitting in the fridge for a couple of weeks.  Then I take them out and leave them out all day and it seems to be perfect!!!

This is what I had always thought worked as well.  In fact I kept the 'good' eggs in the fridge until just before expiry and when it was time to use them they were 8.5!!! 

I wonder why there is such a difference.  I know that if I have my eggs for more than a week I cannot use them.  What type of eggs are you using?  Maybe it is just these free-run eggs that I am using.

cold eggs= lower pH, the older the egg the higher the pH.  If an egg is cold it cant sit out on the counter for longer than 4-6 hours because it will spoil.

The way an egg works (as described in the ttc boy faq) is an eggs surface is covered in pours.  These pours help to 'vent' the egg of its carbon monoxide.  The release of this gas raise the pH of the egg.  You NEED to wash the eggs to clear these pours so it can vent.  Cold air make the pours smaller.  This is why a farm fresh eggs (never been refrigerated) is best.  Also why pasteurized eggs are so great (pasteurized by high heat but not cooked)

Well, for my attempts, I used pasteurized EW's in the carton and I have had them for almost 2 weeks.  I took it out of the fridge and they were 9 already.  I let them sit for 2 hours and they were 9.3.  So, I was lucky!!!  Last time, my eggs were all low and I kept going to the store and because they were all fresh, the ph was still low!!!  I was so frustrated!!  I just learned to buy them during the beg. of the 2ww.

Tamara could you please put that explaination of how an egg works in the ttc girl section too?
