we had four hens and a few months ago one died. it didn't seem to faze the others. then about 10 days ago another one died. we had a necropsy done and turns out she ate a piece of wire that punctured her stomach and she got septic. since then one of the remaining two has been depressed. i thought she might be sick but she isn't. just doesn't eat much and holds her tail feathers low. she also isn't laying eggs. i'm sure she misses he friend. is there anything we can do for her? or does she just need time? i feel bad for her? any suggestions will be appreciated. thanks
