Hello, I brought home 6 Road Island Reds chicks Friday. They are about 5 days old. One was out of it. Slept while still standing. It would drop its head down. Did not really care when I picked it up. It was dead Sat Morning when I checked on them. Another chick is showing the same signs. Starting to sleeps while standing. It's wings fall down to it's side. It drops it head down but keeps it off the bedding. I'm now hand feeding it water with sugar and vitamens. It's poop is clear. What could it be is it me or desease? Using baby chick feed. Changing the water 2-3x a day Using chicken bedding I have them in a 2x3 plastic storage bin. 150watt heat lamp. Temp is good and the other chicks seem happy. What should I do??
