Out of something like 7 dozen eggs set in 4 different hatches I have not had ONE hatch!! NOT ONE Yes from time to time I have had some problems with temp and humidity, but from what I have read on here it should not have been enough to damage all eggs that are set. Many times when I first candle at day 7-10 over half of the eggs are duds. There will be nothing, or a dot and no veins, or bloodrings. I will usually leave the ones with the dot only to find out at day 17 nothing has changed. Each dozen eggs has been purchased from different people, so I am not getting the same batch from the same person each time. So, my question is; does anyone know how to find out which USPS have x-ray machine and routinely x-ray everything? I haven't checked the website yet to see if they tell, but I am guessing they don't. I am sure that if you mark "Please do not x-ray" the first thing they are gonna do is x-ray, since that will just be suspicious. Did you ever think terrorist activity would affect hatching eggs!! I have hatched local eggs, that I found lying around at a barn, and had a 100% hatch. So I know I can do this, at least I think I can! I would love to be able to blame the x-ray machine and not have to take full blame for this. Some eggs I know are damaged from travel, but when air cells look good and eggs arrive in what looks like good condition you would think I could at least get ONE egg to hatch! So any ideas about finding info on the USPS stations that x-ray?
