[THC] Too much yeast?

[jeff at topdogproductions.biz]

Have a question...my fermentation took place nearly 5-6 days after I  
had sealed it in the fermenter and I didn't think it would start  
because maybe I had added the yeast when it was too hot. So, I ordered  
more yeast. When we got the new yeast 6 days later I didn't even think  
to look to see if had begun fermenting because I just 'knew' it hadn't  
so I asked my wife to go ahead and take care of sprinkling the new  
yeast over the top and reseal the bucket. She comes back and tells me  
she did that and that it looked like it had a 'head' on it. I froze a  
bit wondering if we had just added too much yeast - two packets now.  
So, I'm asking if my batch is bad now because of that? IDK.
