Bald spot?

[goodwiab]

Hi!

Today I noticed this little bald spot above my easter eggers eye. It's not red, nor did she have any problem with me touching around it (thoroughly searching for mites/lice to which I found none). I have seven other hens in her Coop/run all of various breeds. I haven't noticed any pecking but I'm wondering if a bit of yogurt got on her and another one just went to the extreme of removing it? Has anyone ever had anything like this? I just feel it's a bit early for molting and what a random spot to do so...

I plan on monitoring but just didn't know if anyone had ever seen this.

Thanks!
