The egg may or not be Russian. My thoughts are that it is.
I also think the egg is written in Latin.
This is what Wiki says about Russian Cursive:
'Russian (and Cyrillic in general) cursive was developed during the 18th century on the base of earlier Cyrillic tachygraphy,[2] re-shaped under the influence of contemporary Latin-based cursives.[3] It became handwritten counterpart of so-called civil (or Petrine) script of printed books. In order, modern Cyrillic italic typefaces are based (in their lowercase part) mostly on the cursive shape of letters.
The Latin influence on the Russian cursive resulted in numerous characters that are similar or completely identical to Latin ones'.
