I got a blk Australorp from the feed store 2 days ago. I just noticed that one of the chicks has a crop that sticks out more noticeably than any other chick I have had ( I am still new at this). Could it have sour crop? It eats and drinks, its poop is stinkier than the rest( there are only 2 others in brooder) When I first got her she slept more than the other one I got at the feed store. Her energy seems better today. I don't know how old they are. I think 6-7 days old? I am not really good at posting pics Does this sound normal? Am I just an over anxious chicken mama?
