I just got a trio of Ameracaunas from a local person (who ordered the chicks from a hatchery) two days ago and one of them has fallen ill. She was standing yesterday but today she can’t stand, isn’t eating and is overall very lethargic (eyes closed, head drops to the ground). If I hold the water dish to her beak she’ll drink a bit but that’s it. I initially dusted them all with DE and added Save-A-Chick to their water. Not sure what to do next since I don’t know what is causing the problem. I’ve tried to contact the seller but haven’t had any luck so far. Any ideas would be HUGELY appreciated. Thanks in advance!!
