Are these eggs viable?

Strange markings on these eggs with some translucent speckles. What is going on here and are these eggs still viable for incubation? Thanks!

They look really porous. What are you feeding the hens? I bet they need more calcium in their diet. I wouldn't incubate them, bacteria enters the pores and causes deaths

I dont know, i got these from a friend to hatch. Sorry i know they are an EE xSilkie cross but thats about it.
