What are these spots on my eggs?

[Tereasa]

The last few days when I have collected my eggs, there have been a few with tiny brownish spots all over them, it comes off when scraped. Can anyone tell me what this is? Is this normal??

There are two possibilities. One is that your hens are spritzing on the brown egg dye unevenly. For awhile one of my hens laid spotted eggs. Read about how a chicken colors their eggs here:

But, the other not-so-nice possibility is that your hens have a severe infestation of mites, which are tiny blood-sucking creatures which congregate around the vent. They only come out at night, so you might not see them. But, when an egg is laid, the blood from the mites and the damage they cause, gets smeared on the eggs. (This is not the same as an occasional red streak seen on eggs, often on first-time layers.) If you take a flashlight out to the coop at night you'll see mites on the roosts - look like crawling black pinheads. In a bad infestation, you'll see them during the daytime and on the hen.
note: mites are not the same things as lice! To see lice photos go here:
