We butchered our first round of chickens this weekend and I'm worried about busting open the intestine or poop leaking from the vent. On a few birds there was some sort of greenish/brown liquid, a bit textured that either came out of the chicken as we were processing or after gutting it. We did our very best not to rupture things as we were pulling out but i'm worried that we did. We rinsed everything and now the chickens are laying in ice water in the cooler. Are they still safe to eat? Please help. Thanks.
