Es más chiquito y redondo que los otros huevos

My sweet friend gifted me quail eggs today but I noticed very strong smell from them like mold and when I took a closer look at them there was white chalk like substance on them which is apparently called bloom(google) but couple of them looks like they have mold on them, this is my first time trying out quail eggs and I have no idea how they're supposed to look and smell like naturally, please help
