So one of my white leghorn hens went and died on me. The rest of the flock seems fine. I noticed some green poop in the vent. Did not seem obstructed. I went to the store to buy some antibiotics and anti worm meds but it died by the time I got back. I did a cursory check and did not notice any trauma. Of note I have two other white leghorns and they do seem thinner than my other fat hens. I am wondering if there is a weakness in the breed. So, anyway I want to cut the bird open to see what I can find. Any tips on what to look for and how to determine the cause of death?
