I agree. I rather felt that way myself. I expected them to lay blue eggs. I mean, I could understand some laying green eggs, given color bleed, or putting a really nice green egg hen under a double blue rooster would give green eggs, etc, but absolutely not brown. Given that blue is a simple dominant it should not have been hard to ensure that you have a double blue rooster over your hens before you sell if you chose to go that route (or vice versa).
