That's not the reason to do it, that is just a side effect. The daily cool down allows the eggs to develop better and the hatch rate is up a lot and the mortality is down. I'll make do with an extra 9 hrs hatch time in order to get these great benefits. The mortality is down because a lot fewer die from day 18 on until hatch and don't usually drown with a lower humidity rate of 55% up to pipping. It raises automatically when they start hatching. The moisture of the egg etc. I'll be keeping my fingers crossed on these. My first time of doing it. I'm so new that I've had 4 almost duds on shipments. Two didn't hatch at and the other 2 hatches only gave me 2 out of 15. I ordered from 2 guys and their packing was wretched. I told them about how to do it better and they sent me the new shipments with exactly the same shipping method. One was a real jerk. I ordered white rocks and they were duds. So he shipped me more and the two that hatched were black mutts. And one egg started smelling at day 3 and was black inside. Coincidence about that after I complained? Sure, I'll bet.. But my first 2 shipments were wonderful. I ordered Super Blue egg layers from DMRippy and she packs good and they were 11 out of 14 and 11 out of 18. That's why the next 4 shipments were SUCH a disappointment. Boohoo, DMRippy is retiring from chicken selling. Selling out I think.
The eggs in lockdown were sent from a distance of about 6 hours by truck. Post Office. I sent her a foam insert and she packed it in a 12" x 12" x 5" box at a charge of $15.75. I paid about $8 for the insert to be shipped to her. So my total cost for these are $38. All three of the Lemon Cukoo Orphingtons are in great shape and she said they travel well and hatch easily. Four of the 12 Basques were clear. Only one was fertilized. I'm not crazy about the Orpington because it looks so much like a Buff, from the picture I've seen, but they may be a great bargain in the long run. Seeing double so I guess I'll go to bed.
Oh, oh, almost forgot the MOST important thing. I got my smart phone today and will be able to learn to post pictures. Woohoo. I've been looking forward for this a long time. I know nothing about how to work it yet. Never used one before. My regular little cell was so easy. But I'm thrilled.
