Re: Handling queen cells: 5th and 11th day
Perhaps someone who has studied this can give a more specific answer to the question of exactly when they are most easily damaged. What I have heard is that about day 8 and 9 is when the wings are developing and any sharp jarring motion may lead to a damaged wing and a resulting virgin unable to mate. I think it is prudent to handle all capped cells with extreme care until they have had five full days after capping to mature. Your question about whether a damaged queen cell can be repaired is pretty hard to answer as it assumes all damage is the same. I consider them worthless to the extent that I wouldn't want to count on them.
