I have a russian and I noticed a small red spot on the side of her head. I just wondered what it is. It doesn't seem to bother her. She is eating like normal.
I can't really make that out, too blurry. But I am aware they don't exactly cooperate with up close photos. It could be a bug bite or maybe an abscess? A possible scrape from withdrawing into the shell or from the enclosure?
I would seek out Yvonne...site admin and a wealth of knowledge.
Although as darkfire007 says it’s really hard to see, it could possibly be an abscess and it looks kind of like a lump.
A better picture is needed and so is the advice of @Yvonne G
