Yes it does!!
You have clearly read quite a lot in an attempt to solve your egg mystery, and yes the subject is fascinating! You may have already learned that sex reversal is gradual, but since Vick was not in your possession and care since he was 6 weeks old, it was Possible that it occurred with him, though it usually happens with older hens.
Going back to the egg mystery, opossums eat an egg by biting into it at the middle and cleaning out all the contents, and I believe rats do so too, so as someone mentioned much earlier in this thread, a rat or small oppossum may have been the culprit. But to offer you further proof that you weren't "crazy" to believe that Vic could have possibly laid the egg, there was a case back in medieval times (1400s) where a "rooster" was tried and found to be a witch, then burned at the stake for witchcraft. That was an infamous case, but it Can occur. So just saying, if Vick had in fact laid the egg, it would have been a very rare occurrence; but not impossible.
