Not sure what you can tell, sorry for crappy pics. Is this the beginning of an infection? 6 days in secondary on cocoa nibs. Starting to see some bubbling around the nibs and suddenly I have activity in the airlock once a minute or so when I had nothing past few days. Infection or just oils and whatnot from the nibs?
Sorry man, can't really tell. It could just be off-gassing. Maybe the temperature changed in the room it's in, or maybe the air pressure changed. Many reasons bubbling would start up a few days after having put the nibs in. Could have just taken a while to build up the pressure again.
Try your best to get a better photo. The first one I can see the white foam, but can't really tell if it's foam, or if it's a pellicle. It's just not clear enough. The second one I see even less foam, but it looks more like foam and not a pellicle. It seems like simply just off-gassing as of right now. Only time will tell.
Did you soak the nibs in vodka or something first? Or roast them or something?
There seems to be no krausen ring, so I'm going to assume that's a secondary vessel. If you do end up with an infection, you'll be wise in the future to make sure that you can fill it all the way up to the next in a secondary. Or at least add some more fermentables in. Otherwise you're pretty much just asking for an infection.
