Hello. I adopted last Friday two Ayam Cemani 8 week old pullets. They were doing okay but two days ago they started to act a bit strange, they were eating and drinking but one specially was constatly fluffed up with her head close to her body, but still moving around. She was dead this morning, no mites, vent looks fine. The other one is exhibiting a similar behavior. I’ve given her electrolites, scrammbled egg and placed her in the sun. Any clue to what could have happened? The breeded says the rest of the flock is fine. I did change their feed suddenly when I brought them home. Could that have been a problem? What could I do to bring the other one back to health, and since she’s by herslef now, should I mix her with the bantams? Or bring her inside for the night? Thank you for your help.
