Hi!
It definitely looks like there has been development in some of your eggs, at least from what I can see in the photo. At the 9/10-day mark they do tend to be slightly more developed, but that can be temperature dependent. What temperature are you keeping them at? Also, have you seen any changes in the eggs these last few days? In my opinion, I would keep an eye on them (or better yet take daily photos!) to spot development. I'm not an expert, though!
