Hand picking eggs is a very tricky thing to do, and I can't imagine the eggs being okay after that. They are so very fragile as it is, and the only way I transport eggs is I take whatever they are stuck to (plants, ornaments, rocks) out and put them where I want them. I tried scraping off some eggs from the tank wall with a credit card VERY carefully, but hand picking?! You can squeash them so easily without noticing, and the smallest pressure on them can cause tremendous damage....
Only time will tell if some damage was done, I would say....
