Nice! Congrats! When my Cuckoo Maran started laying she had some light eggs just like this. She layed for about a month. Then took a short break... When she started again they were way darker. I didn't know that could happen.
My Cuckoo Marans Gertrude (Gertie) laid this egg. I'm disappointed in the color, it's barely darker than my other brown layers. I'm pretty sure this is actually her third egg. I found a broken egg under her roost and my mom had 4 eggs (I only had 3 layers before that) while she was chicken sitting last Saturday. Now I'm on the countdown for my Americana Hazel to start laying. She did here first "squat" yesterday.
