I'm new to this, this is the first time I've had chickens etc... A few days ago my son tripped over a feed bag and landes square on one of my Cornish Meat birds... It flopped around for a little while, threw up and then got up and tried to walk but couldn't very well... Eventually it seemed to be doing better so I thought maybe it was OK... I wasn't surprised when I saw a bird dead in the coop in the morning... But I was surprised that a second bird died later that afternoon... When I inspected the bird I found a prominent green mark that looks like a bruise on its hip... (I'll try to upload a picture...) Anyone seen this before? Would it be safe to eat? Are my other birds in the same coop in danger? Help!
