I have a flock that is 1 year old. I have found over the last week or so some bloody shavings in the nest, a slight bloody stool and a few piles of possible liquid stool. None of my birds appear to be sick or abnormal. I also haven’t gotten an egg from my blue australorp in over 1 week. And the last egg I got was grayish from her. She could be laying somewhere else but I do catch her in the nesting box also. So many weird things going on. I don’t think any longer they have coccidia because no one is sick. Do you think worms are the likelihood or anything else you suggest?
