It looks like there's something going on in there...I wouldn't give up on it til it's way past due. I did the same thing a couple weeks ago, thinking I had bad ones...unfortunately when I cracked the first one to make sure, there was a perfectly good developing baby inside :( I put the rest...
First, I had my thermometer taped to the top of the incubator, so for the first week they were only at 91 degrees. Realized my mistake and corrected it, but thought the instructions said to remove the humidity the last three days, OOOPS. I had only filled the resevoirs a couple times anyway...
