Wouldn't eat or drink even after trying many times showing them. They usually follow what the older chicks are doing. They will run with the other chicks but they don't lay down and just stand there and fall asleep. The other chicks will move to the other annex of the brooder and they just continue to stand there. When I wake them they run to the other chicks and it starts all over again. I noticed the symptoms in the evening and they would be dead in the morning.
