Even Flies Like Rainbow Chicken

I always buy the 4 + 4 packs for my family, because they are (usually) of the highest quality and just perfect for us. However, this time I was let down badly. I am still grossed out thinking about it. As I opened the bag to prepare dinner, I realised that there weren't 4 + 4 pieces, but rather 6 + 2 and they seemed a bit more fatty than usual. I specifically buy it like this because my husband likes the drumsticks. However, it's not the end of the world... so I continue unpacking. Then I stick my hand in to take another piece and there's this big ugly fly on it. UGH! Last piece out of the bag, another dead fly in the bottom of the bag. This is definitely not the quality I'm used to from Rainbow. I'm disturbed, as we buy all the Rainbow products and now I'm concerned about how clean the factories are... ?
