Strange looking eggs

[chickinlittles]

My light Brahma has only been laying a couple weeks And had had very normal looking eggs I until her last two this past couple days. The shells are very rough with lines and crevice like formations. I am transitioning off starter to layer and am currently on about 1/2 and 1/2. they get free choice oyster shells and do eat them. Anything I should be aware of here or just her starting up and getting going on egg production?

This article should shed some light. It looks like your egg is what they call a "Broken and Mended Egg". As a young layer her body will still be perfecting the process so I'm sure it's nothing to worry about.
