Hi All
I offer shipping with or with out the shipping warmers, what ever is preferred by the buyer. I use 72 hour warmers and have not had a problem, however I have had a problem with extremely cold/frozen eggs due to the postal service mishandling (eggs that were left on my door step even though the box said 'call for pick-up'). Having said that, I will say it is
important how you place the shipping warmer. I don't ship in a medium box (and I don't use egg cartons to ship). I always use the large boxes (not flat rate) and single wrap in
large bubble wrap. There is always several inches of shredded paper on top of the bubble wrapped eggs. The shipping warmer is taped to the top of the box or in its one flat rate cardboard mailer so it will never come in contact with the eggs. It will only raise the temperature in the box 10 degrees at best. (Not saying it's right it's just the way I ship.)
According to the postal service packages are never left sitting outside and they are always 'in route' to their destination. However, the backs of the trucks are not heated neither are the opened docks. I still believe we can do absolutely everything right and the bottom lines is the hatchability depends on how they were handled on their trip.
I believe shipping warmers are a preference and I am OK with it either way. I believe it is up to the buyer how they would like them shipped, as they are usually the ones assuming the responsibility of shipped eggs. (Sorry! I just needed to add my 2 cents
)
You all have a wonderful evening!!
