Jason, what day/week are they at right now?  
I am just wondering because if I recall our hatches shouldn't be too far apart in age.  I am currently at 5 weeks, and haven't seen any loss in the post metamorphsis stage yet.  All the ones that I have lost so far have been pre-meta.  Basically, I am looking to see if there is anything that I need to look forward to in regards to loss.
