Made my wort 2 weeks ago and heard it start to ferment and I opened the box I had it kept in today and noticed the airlock overflowed. Is it still good to move into second fermenter or is the batch ruined?
I would go ahead with your plans and finish the beer. It is likely there is not any contamination. Being in an enclosed box would protect the beer from any fruit flies and floating particles in the air that could possibly carry bacteria.
You have patience to not have even sniffed the airlock for two weeks.
