We had two EE babies (days old) that I thought had splay leg and curly toes, they were sitting on their hocks, "swimming" to get around, and not really interested in eating or drinking. I hobbled them, gave them booties and helped them stand to drink/eat (one would drink occasionally), both died. We also had an Ameraucana and another EE (days old, same hatch as the babies above) that walked fine but ended up dying. They both started off seemingly fine, the Ameraucana started sleeping a lot the day after hatch, had labored breathing and her neck craned to the right, she died at 2 days old. She had fluid coming out of her beak when she was removed from the brooder. The EE was fine 7 hours ago, he had been eating and drinking, walking, playing, etc, no sign that he was sick. I woke up this morning and he was dead. He also had fluid coming his beak when I picked him up. What is going on with my babies? How can I treat them so more don't die?
