Hmmmm...do they have a catagory for Mini-eggs

Our chickens have been having a rough summer. Between molting and the extreme temps I was getting one egg a day. They've finally finished molting and I've been turning the sprinkler on for a few minutes here and there throughout the day and I've been getting 5 eggs a day...Yesterday I found this little miniature egg, hmm....I know they have X-Large Eggs, Large eggs, Medium eggs but is there such a category as a mini-egg? I guess I should give the hen credit, at least she tried, lol...I just hope this doesn't become a habit with her!
