Do Xrays cause eggs to not develope? I just got 36 eggs 15 did not develope at all. The air cells were intact and when I cracked them open everything looked in very good shape except they didn't develope. My eggs are incubating right along side of them and they are growing very well. I had asked that the words Do Not Xray be written on the box but it did not happen, otherwise they were well packed.
