It depends on your personal digestive tract (and that of anyone you're going to feed it to) as much as anything, IMHO.
If you normally keep things in the fridge for longer than "they" say you should without undue intestinal repercussions
and have been very clean in processing and packaging the chicken, then I say do whatever seems sensible to you.
If you typically eat things within a day or two and your tummy does not have extensive successful experience with stuff sittin' around culturing up bugs for longer, then it might be a bit iffier, you'd just have to decide whether you want the risk of a) food poisoning and b) if you *do* get food poisoning, probably wanting to throw out all the rest of the meat.
I try not to age things (or just forget 'em in the back of the fridge <g>) for as long when I'm going to be feeding them to other people as when they're just for me or immediate family.
JMHO, good luck, have fun,
Pat
