Is this chicken safe?

First off, I am a pastry chef, and my first thought is, when in doubt, toss it out. I have very little experience with chicken. I am also obsessed with trying new things, in this case silkie chicken. It is a breed of chicken with black skin, meat, and bones, although the color can very from grey to black. I bought it from a new Asian market that just opened up, it was pre-packed and frozen in a tight wrap like you would see at the store. I bought it Wednesday I think and left it to thaw in the fridge until today. I opened the bag, removed the head and feet, and the wind pipe. The smell was very strong, and not pleasant, I would have to say musky with a touch of egg. The skin was a bit slimy, but the slime seemed to be gone by the time I was done cutting heads and feet off. Since the color is dark, I cant tell from that, and the strong smell has persisted on my hands after scrubbing 3 times and doing the dishes. Another note, the bird was an import from china, it wasn't USDA inspected, instead it had a Buddhist exemption tag on it and something saying it was inspected back where it came from.
