vpatt...it is unlikely you hurt anything with the chicks as they are amazingly durable at the peeping stage when within the enclosed shell.
I have learned it is best to avoid touching the eggs those last 48 hours to hatch as the chicks are moving into position and it is best to not disturb them...however sometimes you have to do a quick tidy if mom messed in the nest....and if no one is hatching a quick check and tidy seems to be okay.
However I found it is crucial to avoid looking once they start pipping as you can creat a big change in humidity within the shell and cause a shrink wrap situation with a chick...something I did this summer in an emergency situation trying to save a chilled chick who had fallen out of the nest insert and was thoroughly chilled.
I knew what I had done at the time as my normally irritated but stoic Silkie was panicked and frantic to get back to the chick under her who was emerging from the shell. I had never seen her so desperate. Though half the shell was gone and the membrane pipped, that chick never was able to break through the membrane as I discovered hours later it had become like glue. I ended up finally intervening and doing a hatch rescue which fortunately ended up with a healthy chick but I learned a valuable lesson in not lifting up mom indiscriminately.
