So here is the situation. We have (had) 5 chickens, 2 EEs, 2 Buff Orpingtons, and 1 Barred Rock. Recently the Barred Rock passed away out of no where. She was healthy and active before, then one morning we found her dead in the coop. Took her in for a necropsy. No trauma, no broken neck, not egg bound, no anything. Fecal was negative. Sent tissue off for a pathology screening just to make sure it wasn't something else but if that's also negative we have no idea what happened. The vet said her intestines looked pretty torn up (which is why we figured the fecal would show something). Anyway, after the death, the other 4 girls have had some issues. Right away, one of the buffs became broody, but she was guarding invisible, imaginary eggs and wouldn't leave the nest. She was even sleeping in the nest and not up on the roost with the others. One night, my husband went out and picked her up and put her up on the roost with the others. That easily broke the broodiness. But, NOW, since the death, my 2 buffs aren't laying anymore, at all. The EEs haven't started laying yet (all 4 were born in April). The buffs however were laying when the barred rock was alive. Now it's like they have no interest in the coop or laying at all. They don't even make nests in the bedding like they used to. Is this normal? Are they grieving or just stressed because of the death? None of them appear to be sick at all. They all look happy and healthy. All are eating and drinking, and eating oyster shell free feeding.
