How much does 7 eggs weigh in ounces?

Eggs are sorted by size before packing. There are small, medium, large, extra large and jumbo. Some places you can buy pullet eggs which are smaller than small.

Minimum weights per dozen are : Jumbo (30 oz.), Extra Large (27 oz.), Large (24 oz.), Medium (21 oz.), small (18 oz.), and Pee Wee (or pullet) (15 oz.)

So, large eggs are 2 oz each, and medium are 1.75 oz.

The above is true for the weight of the egg AND the shell, but if you want to know the weight of an egg out of the shell (large, since their most common) it weights about 1.7 oz.
It depends on what size the chicken egg is. A normal chicken egg would be about 1.70 ounces. A large chicken egg would be 2.125 ounces. A extra-large chicken egg would be 2.20 ounces. Finally, a jumbo chicken egg would be 2.5 ounces.
