Young hen, not yet laying was dead this morning. No symptoms or any thing wrong the day before. She didn't roost in the normal place but low to ground, 6 inches. We put them in a small mesh dog crate at night to keep them safe, and let them out in morning but not as early as they would like. She seemed subdued and docile but it didn't seem a cause for alarm. They usually are a bit resistant to be put away. There are 3 left and they seem fine. Any suggestion??? I give them weeds from the yard, also mangoes and some avocados. Should I open her up and look for anything? Should she be cooked and eaten by the dogs? Thanks for your help!!!
